Undertale Walkthrough: Easter Eggs Guide

Main Walkthrough

Odd and ends! Bits and bobs! Stuff! You can find these things here. (And if you have more to point out to me, feel free in the comments. I have no doubt I missed things of interest.)

The Ruins

- Try naming your character as people from the game. In many cases you'll be outright refused, mainly in regards to major characters - Sans, Toriel, Flowey, and Gaster in particular - and in others you'll be allowed, though not without comment. Entering the name 'Frisk' will also trigger Hard Mode for the duration of the Ruins, bringing in enemies from the Core.

- During the, ah, 'fight' against the Puppet, you can get a range of different responses from Toriel, depending on how you deal with the situation. Whiffing your hits until the battle ends gives the funniest responses. (Thanks to Florelyang in the comments for pointing this one out. And no, killing the Puppet does not count against a Pacifist run, so don't worry.)

- You can 'spot' Toriel behind the pillar in one of the first rooms of the Ruins when she runs off to hide, before she hops out to surprise you. Ellipses!

- The first proper fight you'll hit is a battle against a Froggit. If you do anything but kill it with attacks Toriel will show up and glare it into leaving.

- If you wait in the room where Toriel told you to wait, she will, eventually, give you a phone call.

- In one of the rooms you'll find three Froggits. The first seemingly won't be there if you've spent a lot of time skipping through text, which makes sense since he hates when people do that. Another mentions that there are four Froggits in the room; the fourth is hidden in the cracks on the walls. The last allows you to change the font colour of Spare-able enemies from yellow back to white, or to pink.

- Whether deliberately or not, Napstablook's theme appears to sample some of the midi sound effects from EarthBound, most specifically Venus' singing voice.

- There's a spider bake sale in the Ruins. Purchase one of their food items and keep it and you can skip a battle much later on in the game.

- A minor one, but if you opt to sleep in your bed after you reach Toriel's Home she'll leave Butterscotch Pie on the floor for you. This is an extremely good healing item, and should be saved for the final battle against Asgore. You'll also get a brief message from sleeping in the bed. (Not sure if this only happens before or after the fight with Toriel. I'm pretty certain I got it before, but Kristen in the comments says after. Try both? It's not like it's a long walk.)

- It's virtually impossible to lose the fight against Toriel, as she'll purposely miss when your health gets too low. You can die, but you need to lose a lot of health during her last attack before she switches to non-lethal fireballs. Her expression when you do manage to die is priceless. (If heartbreaking.)

- Also during the Toriel battle, you can end it in a single hit if you attack her after Sparing her into giving up - but slicing her just before the battle's going to end. Ouch. No Mercy run after all?

- If you backtrack through rooms in the Ruins - in particular, the room with the Froggits - you may see Flowey disappearing into the floor on the edge of the screen. This is true of other areas in the game, as well.

- Eventually you'll receive some new equipment, allowing you to unequip the Dirty Bandage that starts as your default armour. You can thereafter use the Dirty Bandage as a normal item to restore 10 HP. (Thanks to Charlie Fire for pointing this one out in the comments.)

Snowdin

- You can use the Stick (the first weapon) to appease the many doggish monsters in this region. Funny times. It needs to be used as a normal item for this to work, not as a weapon.

- There are a number of cameras in Snowdin in hidden places. The most prominent is in a boulder right beside the exit from the Ruins.

- If you reload after first speaking with Sans and then speak with him again you'll get some alternate dialogue.

- There are usually alternate ways out of Papyrus' puzzles. On the coloured floor tile trap, for example, you can keep badgering Papyrus about the rules until the machine breaks down. On a Genocide run you will pretty much automatically skip all of the puzzles, because your character just doesn't give a toss about Papyrus' silliness.

- Speaking of the coloured floor trap puzzle, take a gooooooood, loooooong look at the machine that activates the trap. Does it look familiar? It should, if you've already played through the game once.

- Lesser Dog, a one-of-a-kind enemy that usually appears near a big patch of slidey ice, grows an insanely long neck if you keep Petting him. Spare him once you're done and you'll find him later, building snow sculptures - and the size of their necks will reflect how much you amazed the poor pup.

- Partway through Snowdin you'll find a snowman who will give you a Snowman Piece. If you keep this with you on a Neutral run and beat the game with it in your inventory you'll get an extra message at the end. During a Pacifist run you can get some different dialogue from him with it in your inventory, as well. During a Genocide run you just steal most of his body, resulting in a terrible collapse - and three Snowman Pieces. You. Monster.

- For that matter, if you Spare any / all of the dog enemies in Snowdin, you can find them again later at Grillby's.

- Not far from the long bridge leading to Snowdin Village is a side area with a mysterious cave, and inside that an even more mysterious door. This door leads to the Developer's Room. The only way to open it is to avoid all of the names in the 'Special Thanks' mini game that pops up at the end of a Pacifist run. As far as I know, it remains open on all subsequent runs as well.

- There's a wolf in Snowdin who hurls ice into the nearby lake. You'll see this ice travelling throughout the game, all the way to a dumping point in the Core. The only way to talk to this wolf is to complete a Pacifist run, then head to where he was working during the round-the-world tour that is the ending.

- If you head north through Snowdin Village you can find the launching spot for the boat man's ferry later in the game. It's vacant when you first arrive, but if you haven't fought Papyrus yet you can get a 'wrong number' phone call. It's... yep.

- You can't get a Game Over fighting Papyrus. If you lose he'll shove you in his shed. Keep losing and eventually he'll give you the option to stop fighting. (Seriously, though, he's not that hard.)

- If you Flirt with Papyrus the option to 'hang out' with him after the battle changes into a date. Both are pretty funny.

- During the hang out / date with Papyrus you can visit his kitchen, and when you do so he'll rush in to chat with you about it. Keep entering and exiting the kitchen for some humorous results, 'cause Papyrus has trouble keeping up with you.

- If you kill Papyrus you won't see Sans again until the very end of the game. He won't be happy with you.

- If you go behind Sans' and Papyrus' house you can find a locked door. The key to it is in Sans' room, and the key to Sans' room is... on Sans. You can get it much later in the game. More on that below.

Waterfall

- Make a bridge of Bridge Seeds to the sign in the second area where you must use them and you'll be told that you're a spectacular failure. To the right of this spot is another potential place to lay down the Seeds; this will take you to a bench where you'll find an Abandoned Quiche.

- If you take an umbrella while speaking to the Nice Cream guy, he'll knock 10 gold off of his normal asking price. 'brella buddies!

- There's a little purple dude who will spirit you back across the big gap in the water you crossed on a raft. He doesn't appear until after you leave the area, however.

- If you play Napstablook's music and leave his house it will remain in the background. Get into a fight and you'll get a one-off, hilarious enemy encounter.

- Napstablook will invite you to lay down if you speak to him in his house. Do so and wait long enough for a trippy, ethereal experience.

- Try refusing to give a Temmie a Temmie Flake. Just try it.

- Speaking of Temmies, and Temmie Flakes, you can find the Temmie Village on the mushroom-hidden paths two screens east of the turtle vendor. It's a speshul place. (And the only place where you can sell items.)

- Not sure if this counts as an 'easter egg', but you can sell the Clouded Glasses from the turtle vendor to the Temmie vendor in Temmie Village at a 20 gold profit. It takes a while, but this back-and-forth method grants you practically unlimited gold, assuming you have patience. (The upgraded Cell Phone with two Interdimensional Boxes helps, too.)

- The Temmie vendor will occasionally get really excited about an item you try to sell him, and will offer more than the normal asking price. Refuse him twice and his dialogue will... change. It gets even more insulting after you've sent him off to college.

- The battle against Undyne is a stylistic nod to the battle against Magus in Chrono Trigger in many respects - the battlefield, the setup, the atmosphere, even the dialogue on the save point. There's also a song on the Undertale OST called 'But the Earth Refused to Die', which is similar to Chrono Trigger's 'But the Future Refused to Change'. (Thanks to Sandact in the comments for pointing it out.)

- If you Challenge Undyne she'll increase the speed of her attacks. Plead with her and she'll occasionally reduce the speed of her attacks.

- If you kill Undyne, the 'Welcome to Hotland' sign at the end of Waterfall will not work.

- While 'hanging out' with Undyne you can point her spear at more than just the objects arrayed on her counter. Point at her for some funny dialogue. (Why does everyone seem to view this tiny child as a romantic? Must be a monster thing.)

Hotland

- You can drain the water from the water cooler at the beginning of Hotland and dump it onto the ground. A tree grows here during the Pacifist ending if you do this.

- You'll encounter a mysterious boat man south of the first save point in Hot Land who can ferry you between the game's three major sections. He occasionally gives out hints about important Undertale secrets during the trips.

- Alphys will quietly give you the answers to Mettaton's quiz during your first battle. Watch her hands.

- Speaking of Mettaton, it is impossible to die during any of his 'shows'. Alphys will somehow save the day every time. This is most striking when disabling the bombs, because the timer slows down substantially when you reach the final ten seconds.

- Assuming you didn't kill Papyrus, you can find Sans selling Hot Dogs...? in Hotland. Buy so many that you have no more room in your inventory and Sans will start stacking them on your head, up to a maximum of thirty. Yes, thirty dirty dogs.

- There's a secret boss called So Sorry near the spot where you can purchase the Hot Dogs. Check the northern boundaries of the next screen to the west, just north of the intersection that goes south. You need to come to the secret room you'll find on the date and time listed on the sign for So Sorry to appear, however.

- You can skip Muffet's boss fight by purchasing one of her overpriced baked goods. You can also effectively skip her by using either Spider Cider or a Spider Donut at the beginning of the fight. Both of these items can be bought cheaply from the spider bake sale in the Ruins.

- At one point Mettaton begins to serenade you during an operatic solo number. This is a direct parody of a similar, slightly more poignant scene from Final Fantasy VI. (Thanks to Dibullba for pointing it out. Man, I can't believe I forgot that. I love FFVI.)

- If you killed the Royal Guards the Nice Cream man will continue to offer his wares just south of MTT Resort. Spare them, though, and they will buy up his entire stock. Oh well, love is more important.

- You can buy a Mystery Key from Bratty and Catty, in the alley beside the MTT Resort, for 600 gold. You can use this on the locked house next to Napstablook's in Waterfall to learn more about a certain robot.

- Using any of the food items from the MTT burger shack during the battle against Mettaton EX will give you a hearty boost to your ratings. The more expensive the item, the bigger the boost.

- Partway through the battle against Mettaton EX you'll be asked to write an essay about what you like best about Mettaton. A jumble of letters will earn you 100 points; writing 'legs' at any point will get you 350 points. Swear, however, and you'll lose points instead.

Home / True Lab / Ending

- If you close the program and reload it several times after receiving 'judgment' from Sans on a Pacifist run, he'll start giving you a series of code words. Keep doing this (preferably having saved at the save point just before Sans) and he'll eventually give you the key to his room, back in Snowdin Village. Don't save between visits with Sans - just turn the game off after you're done talking with him. (You can also do this on Neutral runs for different dialogue, but you won't get the key.)

- If you use the Butterscotch Pie during the battle against Asgore he'll receive a permanent penalty to his attack and defence. You can get similar results by talking to him repeatedly.

- The ending changes depending on which bosses you killed, as well as how many monsters you killed along the way.

- You can drop Undyne's Letter after she gives it to you (though she'll yell at you if you try to ditch it on the screen where she's standing). Go back and ask for another and you'll receive Undyne's Letter EX, which you cannot drop. It's too strong.

- You can sleep in one of the beds of the True Lab. Remain motionless for a while and a ghostly presence will reveal itself.

- During the epilogue of the Pacifist ending you can wander across the entirety of the world, and everyone (save perhaps one dude in Waterfall) will have something new to say, particularly the more important NPCs. You can even reenter the Ruins... and if you bother to walk aaaaaaall the way back to the beginning, you'll find the most informative NPC of them all waiting to gab with you.

W.D. Gaster

Lurking in the background of all of this funky stuff is a spooky, mysterious dude named W.D. Gaster. He's a presence in Undertale whom you might completely miss if you're not sifting through the game with a fine-toothed comb. Gaster remains a major question mark for players of Undertale, and there's currently a manhunt-in-progress for the guy. I suggest checking out this highly-informative Steam page on Gaster, 'cause frankly, I got nuthin'.

  1. There's an easter egg in the ruins you missed.

    In the room with the three froggits, walk towards the end of the hall that progresses you towards toriel's house until you get a phone call from her, warning you about carrying too many things. After you have gotten this phone call, walk back towards the way you came. You will probably have a monster counter along the way. It should not affect the easter egg appearing.

    Keep your eyes on the left edge of the screen. As the entrance comes into view, you will see Flowey briefly before he sinks back into the ground.

    He has his eyes on you...

    After you have encountered this easter egg, exiting and re-entering the room will not get it to appear again. However, if you allow yourself to be killed in a battle and go back to a save point before you saw flowey, he will appear again.

    1. Yep, I got that one. It's right at the bottom. Thanks for the extra detail, though. I'll expand it a bit to include this stuff. I saw in him Snowdin, too, but I can't remember exactly where...

      Delete
    2. it can happen in lots of rooms, actually! i saw him in waterfall, it was terrifying. and in game grumps playthrough they also saw him in waterfall (in a different room, btw). you can find him in most long rooms if you walk fast enough.

      Delete
    3. i also saw him after you defeat mettatonin the cooking show, if you go back into the kitchen place he will be there at the far left staring at you for about a second, and then hell pop beck into the ground. i thought it was really creepy since he stayed there for a longer time staring at you then ther other times...spoopy

    6. I ALWAYS see him after the Mettaton bomb-defusing part. You have to head left from the middle and there he is.

    7. FOUND A VERY HARD ONE
      so... if you spared toriel you can still call her...
      but it says "But nobody came"
      after you call for help in omegaflowey fight he/she says...
      "But nobody came"
      "How Sad"
      ...
      idk if it counts but still

      Delete
    8. You can even see flowey in the room toriel told you to wait in if you go back the way you came you can see him.

  2. "The only way to talk to this wolf is to complete a Pacifist run."

    I've completed a pacifist run, but see no option to talk to the wolf? Can you verify how this is done/what the wolf says?

    ReplyDelete
    Replies
    1. I should clarify that, yes. You can talk to him during the ending sequence where you're walking around the world. I believe he says something about getting a new job. Nothing compelling, but I spent the whole game wanting to talk to that guy.

      Delete
    2. Gotcha, thanks for the clarification! I, too, was interested in talking to him, and totally missed him when I went back to the beginning to talk to Asriel.

      Delete
    3. I can give you his exact words: "Ice Wolf no longer has to throw ice. Ice Wolf can take a break to buy some pants now." XD

      Delete
  3. I thought there was a small easter egg just before Undyne. The way she stands before the fight is just like Magus when you fight him a second time in Chrono Trigger, and even the save point says "The wind is howling..." like it does before Magnus.

    ReplyDelete
    Replies
    1. Yes, I noticed that too. There's a song named after a line from Chrono Trigger, as well. Not sure if they're substantial enough to stick in here... thanks for pointing 'em out, though. I'll ponder them both.

      Delete
  4. I have located an easter egg in Sonwdin.
    In Papyrus and Sam's house, during the hang out/date, you may notice Papyrus walking when you enter and exit the kitchen.
    Moving in and out of the kitchen fast enough will lead to him being in perpetual motion. After a while, a ding sound is played each time he changes direction, and he speeds up. When he finally stops, a chime will play, and he says something different when you talk to him.

    1. Thanks! I've heard of that one before, but I haven't had a chance to test it. I'll chuck it in there since you gave plenty of details.

  6. I don't know if this counts as an easter egg, but if you keep the dirty bandage (the armor you spawn with), you can reapply it in battle to heal 10 hp.

    ReplyDelete
    Replies
    1. Ah, yes, I completely forgot about the Dirty Bandage. I'll put it in there. Thanks! If I remember correctly you also get some extra dialogue from Sans if you wear the Bandage for the entire game, but I'd have to verify that.

      Delete
    2. I just wanted to thank you this is so good is it chill that I screen shotted all of it.

  7. In the waterfall level when Undyne makes you fall from the bridge. The cutscene is actually a reference to FFVII when Cloud falls from a walkway into a patch of flowers. Technically could be considered an easter egg for referencial purposes.

    ReplyDelete
    Replies
    1. Also the Drama scene with Mattaton is a reference to FFVI's Opera scene even using a small portion of the actual song and sounds.

      Delete
    2. I'm not sure sure out the dropping off the bridge part, but wow, I can't believe I forgot about the opera scene. FFVI is one of my favourite RPGs evar. Thanks for pointing it out.

      Delete
  8. After the battle with Toriel, go back to the house and take a nap. You will hear a message.

    (I spared Toriel, was doing a neutral run, and this wasn't my first playthrough. I don't know if any of those are factors.)

    ReplyDelete
    Replies
    1. You know, I remember that message now, and I'm pretty sure I got it BEFORE I fought Toriel, not after. Was on my first play through, too. Either way, I'll shove it in. Thanks!

      Delete
    2. You Can get it after toriel says the line with 'go upstairs in your room'. It'll appear every time you sleep from then I think. At least I got it more often then just one time

      Delete
  9. theres an easter egg with the first dummy in the ruins where you choose the fight option several times and purposefully miss (let the bar go all the way across)... after about 7 or 8 misses the dummy will fly away and Toriel will look quite spooked

    ReplyDelete
    Replies
    1. ... huh. Totally did not know that. Will put it in. Thanks!

  10. After defeating undyne (atleast as a pacifist) you shoud go back to the room next to the back where monster kid fel, there you will find something or rather someone... Take a look!

    1. Lol. Set Undyne's house on fire. Then fake attack her. "To the bathroom!" - PAPYRUS.

  11. Another little Easter Egg: During Omega Flowey when he surrounds you with pellets. Keep running into them and Flowey will get annoyed XD.

    ReplyDelete
  12. While doing the Dog Residue farming trick. I figured out that Temmie does not randomly decide when it really wants something. Every 8th item you sell will get an increase in payout.

    ReplyDelete
  13. I dunno if it is worth mentioning , but if you wait some more after Toriel leaves you , there are other calls when we hear the annoying dog taking the cellphone from Toriel and the calls after we hear her trying to get her phone back

    1. I actually waited until it ends... The dogs snores in a hide while toriel got tired of searching lol

  14. When you kill papyrus and go to the waterfall and meet undyne for the First time, you can go (After she stares at you) backwards and you will see papyrus standing in the room where undyne is. Sorry for bad english. I am not from the US or UK.

    ReplyDelete
  15. Not sure if this is one or if it's just something normal but meh I found it interesting. If you play through a second time and reach Toriel's house, interacting with the plant in the tall vase next to your room and the one at the end of the hall near the mirror will tell you something about seeing them before but not being able to remember its name. After you read the encyclopedia of plants on the bookshelf in Toriel's room and interact with the plant again, it'll say "Oh! It's a 'water sausage'". It doesn't count as an easter egg according to my friend also playing it but I enjoyed it.

  18. Once you finish the true ending and go back to the start with the flowers, go behind the character and press and hold Z. The dialogue you'll get is hilarious.

    ReplyDelete
  19. Another pretty cool Easter Egg and useful tactic for Mettaton. If you equip certain items during the battle, you will get huge spikes in rating. Like the Stained Apron for example gives you +1500.

    ReplyDelete
  20. Oh, yeah! The machine really did look like Mettaton xD

  21. On Muffet's bake-sale table, there's an item that is described with the following text:
    "(It looks like some sort of powerful bracelet...)
    (Wait.)
    (It's just a croissant...)"
    This is a reference to The Legend of Zelda, in which the Power Bracelet looks like a croissant. :D

    ReplyDelete
  22. Just encountered this one (doing a Pacifist run):

    When heading into the left side of the Core entrance, you encounter Madjick. According to CHECK, it "only says magic words." It then performs its attack while saying "Alakazam!!" If you try to TALK next, "It interrupts you by muttering gibberish... Its gibberish dizzies you. Your DEF drops by 1." This makes your SOUL spin and inverts movement. Once the attack is over, you're still confused unless you go into ACT and CLEAR YOUR MIND, which corrects your SOUL and raises your DEF.

    I *think* this is a Pokemon reference?? The fact Madjick says both "Abracadabra" and "Alakazam" within his attacks while also having the power to "confuse" you with a non-physical attack makes me think the game is referring to those 3 psychic Pokemon (Abra, Kadabra, and Alakazam), the latter 2 of which can perform the move Confusion on their opponents.

  23. There's another Easter egg. I believe you can get ANOTHER key from Sans. I'm not so sure yet, but if you get the first key from Sans, and unlock the room and the lab without saving, before quitting and reloading back to the judgement hall, Sans will give you another key. I don't know where this key leads yet, I may or may not check.

    [If you let Papyrus alive]
    In the waterfall, where you see Sans with the telescope. proceed to go down 'till Papyrus calls you. Then go back, you'll see a glimpse of Flowey in a sec and disappear .

  26. Uh, something strange happened and I think this can count as easter egg?
    For some reason, i killed Toriel but the scene ripped my heart so I closed the game without saving and I let Toriel live, then in the exit Flowey told me (not exactly, but something similar)"I know what you did, You killed her but you regretted it and saved her instead"and things like "you're playing to be god""You're changing the rules of the place" and more things similar. Anyone got this too...?(sorry if my english is bad)

    1. There are few characters that know when you reset the game without saving and change something, like Sans in the Judgement hall, he'll skip his speech if you already listened to it.

    2. I got this in the demo of the game, being a demo I didn't think about what I wanted to do with it so I just did genocide, I saved it then reset and spared everyone. Flowey told me the same thing he did in your case.

      Delete
    3. It happened to me to, I killed her the first time 'cus I thought I get a choice at the end of the battle. When I got to Undyne I reset, then when I spared her, Flowey said that to.... I think it's supposed to be a part of what Toby Fox had in store for us.

      Delete
  27. There is an easter egg in the ruins, if you are following Toriel to he ruins door and before she gets to it she tells you to go back to your room, if you do go back and sleep a message appears, cannot really remember the whole thing so i would like you to test it since i did not finish the game yet but it goes something like this:"(Your name here) you are chosen to change the destiny for humans and monserts, please wake up"

    ReplyDelete
  28. I guess this isn't really an easter egg and more of a glitch, but if you talk to the guy in the room next to the bridge where monster kid fell and press z/enter next to his 'puzzle' enough times, some times his mouth is still open even after he stops talking. Just thought it was funny...

    ReplyDelete
  29. During a genocide run, if you spare Sans, something hilarious will happen.

  33. When you are in Snowdin, when you reach the puzzle that supposedly looks like "Papyrus's face." One of the trees has a switch on it, and if you press it, you are able to skip the whole thing by pressing the button to finish the puzzle.

  34. It's more a bug, but whatever. During a true pacifist run, during the fight with Asriel, if you Spare Alphys instead of saving her, the game will bug and will lead you back to the Barrier and you'll need to restart it.

  35. Another bug. During a true pacifist run, while you're talking to all the main characters (before Flowey attacks), if you press space, Undyne and Alphys will try to kiss earlier.

    ReplyDelete
  36. If you play the game enough times, it's much easier to do this with the demo of the game, at the start Flowey will say "Don't you have anything better to do?" then the tutorial will start.

  37. In the very beginning when you fight flowery, if you avoid all of his "friendliness pellets," he gets very unhappy. He actually slips and calls them bullets at one point

    1. Yeah, and then when he shoots them at you, after a second he turns them back to friendliness pellets.

  38. There's another easter egg along the path to Snowdin.. in the area with all the snow poffs. If you interact with all of them, the last one will have 30G inside of it.

    ReplyDelete
  39. Dunno if people know this but... After Papyrus's first puzzle, after u saw the ice cream guy. If u can put the snowball in the hole with ease (while its still big) there'll be a purple flag comin out and gives u 2G. If u can put the snowball in the hall after it became really really small and get it in one shot, there'll be a blue flag comin out and gives u 4G. And u can do it endlessly...

  42. You can also type "toby" in the Mettaton essay for even more points!

    ReplyDelete
  43. type his name in the essay

    ReplyDelete
  44. Mettaton talks in morse code, which all translates to 6C704D1E2C95628416D42ED91E3354BD, a MD5 hash which can be translated in a MD5 converter. Doing so gives you a link to an image of Flowey saying "You naive idiot." here http://i.imgur.com/IwoJS3l.png

    1. This was actually faked by a fan. The image was uploaded at the same time that the original Reddit and YouTube video discussing the decryption were uploaded. In addition, md5 cannot be translated that easily, unless you decrypt it from the exact same website that you used to encrypt it.

  46. If you go into Toriel's basement before talking to her, she'll go down to get you. She says something different each time you do it.

  47. I don't know if this is an easter egg,but heck

    if you keep on humming during the Shyren encounter in the waterfall area,it'll become a concert that attracts other monsters and Sans will apparently start selling tickets..

  50. You missed the troll item "instant noodles". Use it once and you'll revive 4 hp in like a minute. Leave and DON'T SAVE and it will max out your HP

  51. OK,guys,really cool Easter Egg: In the Ruins, in the THIRD room with the switches, if you go to the direct left of the pillar nearest to the door and press Z, you fall into an empty room. I have yet to know if after a Pacifist run you meet some monsters there. The sad part is when you get out of there you are teleported to the first room with the switches.

    Replies
    1. If you press any of the switches that you're not supposed to, you've failed the puzzle and it puts you in that room so you can restart the puzzle.

  52. I don't know if anyone has pointed this before or even noticed this, but I noticed that during Mettaton's solo performance or whatever that is, the title bar on the game's window changed to 'UNDERTALE the Musical' and idk about you guys but that's an easter egg for me and yeah, I think it's rather hilarious.

    ReplyDelete
  53. And if you try to sell Ballet Shoes at Temmie's shop, the same thing happens like when you try to sell Cloudy Glasses. At first Temmie will offer you 81 G, but if you refuse they will raise the price to 103 G.

    1. That happens every 8th time you sell something.

  55. At some point before fighting Photoshop Flowey, and after fighting Asgore, if the game is in windowed mode, the title is random letters that keeps changing to different random letters.

  56. In genocide, after Chara erases the world, the game has no title.

  57. idk if someone's even visiting this site, uhh...
    anyways
    I played UT for some time and I like exploring all possible locations
    I found a red guy in MTT Resort, which looks like Hellboy.

    not to mention - if someone didn't notice, Alphys and Undyne are lesbians (wow such surprise wow) and the 01 and 02 Guards are gay. Not sure if it counts as an easter egg tho...

    ReplyDelete
    Replies
    1. I don't think 01 and 02 are gay....BUT I am sure this is an Easter egg: If you listen to all of the echo flowers, you'll hear a conversation.

  58. Oh yeah! I remembered one! I was going to mention the one about going down to the basement of "Home" before talking to Toriel about leaving the ruins, but someone already did.

    INSTEAD, however... I shall mention another little present about Toriel. If you end up sparing her, and feel really bad about breaking her heart (metaphorically), try back-tracking all the way to the beginning. :)

  59. I don't know if other people said this, but In Waterfall, there is a room you can only get through playing the first eight notes of the "haunting song" that echos in the hallway. If you look through the game files, you can hear those eight notes. I don't know which notes, though it's right under one of PAPYRUS'S music things.

    ReplyDelete
    Replies
    1. You cheated. The REAL way to find those eight notes is to actually discover the track "Memory" in-game but giving an umbrella to the sad-looking statue. This track is also a music box version of "His Theme"

  60. Also, when you have to defuse the bombs, the game bomb is Undertale. And if you talk to sans in Waterfall, he will say that an flower has been talking to PAPYRUS. Flattery...(don't know what else).....predictions. That flower could be Flowey.

    ReplyDelete
    Replies
    1. It IS Flowey. At the end of the game when everyone is talking, Alphys will ask how Papyrus knew to call everyone, and he'll say, "A tiny flower helped me." After that, Flowey will appear, which is, I think, enough evidence to state that the flower was, indeed, Flowey.

  61. you can find toriel in a secret room in waterfall

  62. There is an easter egg in hotland where Sans gives you a 'Hot Cat' instead of a 'Hot Dog...?'.
    I'm sorry if it has already been said. I just had to point that out 'cause it just happened to me...

  63. Not sure if anyone has commented this before but I went into the basement to exit the ruins but Toriel will come down and drag you back upstairs. You can get a few messages from her before it just becomes "...."

  65. I know one more Easter Egg: If you dodge the white Love points of Flowey at the beginning, you will get an extra dialogue.

  66. If you kill the flowey boss at the ending and you reset the game, it will not appear never in the future resets of the game

  67. Idk if this counts as an easter egg, but meh. I'm attempting to do a genociede run (omfg I'm suffering so much) and when the time came to "kill" the monster kid, I just couldn't and I spared him, then I beated Undynes ass, and saved, the thing is, genocide run ruined, had to restart, I did and it asked me if I wanted to go again with the same number and in the beggening this two things happened:
    1. Flowey recognized me, he said something like "back again emz (with his psico face)
    2. Toriel remembered my prefference and said she felt like when she saw me, she was seeing an old friend (died). she also remembered that I had killed her the time before, cause just before I started the battle, she said that she saw something in my eyes, and that she felt this was familiar. geez tori, stop making me feel horrible and die am i rite
    *well this is tecnically from the genocide run: only gonna say THAT ISH IS CRAAAZY, it´s FILLED with infinite easter eggs of the pacifist run, and some really sad stuff. Ex: when you fight doggo (the "blind" one) before starting the fight he'll ask WHAT'S out there, and that he got a chill down his spine. Also in Toriel's house, when you see yourself on the mirror, instead of saying "it's you" it will say "It's me, *CHARA*" (name that you gave to your character). really tho, check the GR out, you suffer but there's a tooon of cool stuff to find

  72. Idk if it's been mentioned in the comments yet, but on a Genocide run if you go back to Toriel's house after killing her and sleep in the bed, you'll get the 'game over' speech Asgore says while you're sleeping and if you turn the lamp off/go to bed and it turns off by itself (somehow) instead of the musicbox variation of Home playing you'll get a slowed down, melancholy version of Fallen Down. :'D Sweet dreams, goatmom.
