開発者からのメッセージ

"スプライトリッピングの警告"

バージョン1.00

...and don't even get us STARTED on uploading audio tracks to BrawlCustomMusic!

これらの巨大なスプライトシートをネット上にアップロードしないでください。
ただ、ここで最も奇妙なものが使用されているので、多分それらは、最初のコンテキストで見られると思います。
あなたは一年の最初までお待ちください。
でもあなたが今ちょうどspriter's resourceや何かのためにスプライトをリッピングしている場合、これを使って簡単にするのは気にしません。

abc_1111_0.pngはスプライトリッパー達へ、特にSpriter's Resourceのウェブサイトにスプライトフルシートをアップロードする前に1年待つように指示されたメモである。

Undertaleように、Game Makerで作られたゲームは、各スプライトや文字を個別のファイルとして保存するので、Undertaleは大きなPNG(スプライトシート)にすべてのスプライトを格納する仕組みをとっている。よって全てのスプライトシートをアップロードすると、すべてのスプライトをアップロードすることになってしまうためであろう。

悲しいことにファイルは強制的にファイルリストの先頭からアルファベット順で並ぶため、スプライトシートを探すことが容易い。スプライトは、外部プログラムを使用して文字列名によって分離されている場合は、ファイルのリストにのみ表示される。 これは、それ以降のバージョンで置き換えられた。

Version 1.001

I don't like the b-bepis either!! I-i swear!

 
おれのいっちばん嫌いなものを教えてやろう。

それは"bepis"さ。

あの色、あの匂い、あの味、あの舌触り…

お前、よだれが出てるぞ...

バージョン1.001では先述の警告が、EarthBoundのムーンサイドに居るプレイヤーがすきなこんだてを嫌う男に"bepis"について言及させた時のメッセージを書き下ろしたメモに置き換わっている。 Toby FoxはEarthBoundのファンでありUndertaleはこのゲームに深く影響を受けている。"bepis"とはpenisのスペルミスであり、Toby Foxもこのスペルミスは馬鹿げていると思っていたようである。現在はメッセージが削除されている.

以前のスプライトシートの警告がこの意味の無いテキストに入れ替わったということは、このToby FoxからのEmailと合わせてスプライトシートのアップロード許可と捉えることが出来る。

警告「"ゲームを台無しにしないで!"」

abc_123_a.ogg

''Hello. He-he-he-he-have some respect and don't spoil the game.
It's impossible to have mysteries nowadays, because of nosy people like you.
Please keep all of this between us.
If you post it online, I won't make any more secrets.
No one will be impressed.
It will be your fault! He-he-he-he-ha-he-he-ha-he-he.''
こんにちは。ヘッヘッヘ、
...彼はこのゲームを尊敬している。そんなゲームを台無しにしてはいけない。
あなたのようなお節介のおかげで今日まで"謎"を秘密にすることができない。
どうか、この謎達全ては私たちの間だけにしておいてください。
もしも、あなたがそれをネット上に投稿したら、
私はこれ以上秘密を作らない。
誰も感動しなくなる。
それもあなたのせいで!ヘッヘッヘ

これは、ネット上にゲームの秘密を投稿しないように伝える8つのテキスト読み上げソフトの声の音声ファイルである。

先程も記述したように、ファイル名はアルファベット順でファイルリストの先頭から並ぶため、このファイルの存在をもっとはっきりと表させるためにか強制的に上に来るような名前になっていた。(ゲームのフォルダ内に存在する他のすべてのOGG形式の音楽や効果音のファイルの先頭は、「mus_」または「snd_」のいずれかで始まる。)

このファイルは、2016年1月20日のパッチで更新された。更新されたバージョンでは、ほとんどのオーディオファイルがゲーム内から取り出されている。

Toby Foxのメッセージ

Part of this game's charm is the mystery of how many options or secrets there are.
If you are reading this, please don't post this message or this information anywhere. Or doing secrets will become pointless.
By the way, most of the seemingly unused text/files are used.
If you can find the in-game context for an asset, you can show it off.
But if you can't, it probably means you haven't looked hard enough.
Anything truly unused I'll probably post myself, later.
Living in a world like this, where people can simply cheat out the answers from the code...
your impatience has REALLY damaged you, hasn't it?
このゲームの魅力の一部は、他の設定や秘密があるかの謎です。
あなたがこれを読んでいる場合は、このメッセージまたは任意の場所にこの情報を投稿しないでください。
ところで、一見未使用に見えるテキストやファイルのほとんどは使用されています。
あなたはゲーム内のコンテキストを見つけることができれば、あなたはそれを公開することができます。
だけどあなたはそれらを見つけることが出来ないでいるのであれば、それはおそらく十分に懸命に見ていないことを意味します。
未使用物は、後々私自身が投稿します。
人はコードからの答えをただ打ち明ける世界に住んでいる...
あなたの"急ぎ"がをあなた自身を本当に傷つけることになりましたね?

このメッセージはテキストセグメント(STRG)の先頭に記述されている。 この部位は"gml_Script_attention_hackerz_no_2"というスクリプトで使用され、demonx, demony, demonz, demondの4つの文字列をそれぞれ設定する。(これらの文字列はメッセージの行間にある。) このスクリプトは明らかにクラッカーを警告するためにあり、ファイル"data.win"のCODEブロックとSCPTブロックの最初のエントリに存在する。

バージョン1.001ではこのメッセージがこの様に変更された。

Greetings.
You have made yourself completely clear.
Understood.
I, your humble servant, will follow you to the utmost...
どうも。
あなたは自分自身を完全に理解しました。
よろしい。
私...あなたの謙虚な下僕があなたを追いまわすだろう...

更に先述のスクリプトに設定する4つの文字列もdemona, demonb, demonc, demondに変更されている。 不思議なことに、バージョン1.00のメッセージの最初の行は関連付いている変数と共に残っているが、それらは2436行目(特別な名前を入力した時に表示されるメッセージの間)に移動されている。

未使用音楽

mus_kingdescription

ゲームオーバーのテーマ"Determination"に更にオーケストラ感を加えたもの。 ファイル名に基づいて、Asgoreに関連するシーンで使用された可能性が最も高い。

mus_dance_of_dog

ゲーム起動時にエラーが発生した際に現れる犬が走るタイプのエラールーム内で演奏される。 エラールームはセーブデータの値を弄ることで簡単にアクセスできる。

mus_sigh_of_dog

ゲーム起動時にエラーが発生した際に現れる犬が寝ているタイプのエラールーム内で演奏される。 エラールームはセーブデータの値を弄ることで簡単にアクセスできる。

mus_star

Star Foxで使われている楽器が使用されている。このゲームでは他にMario PaintFinal Fantasy VI, Chrono Trigger, EarthBoundで使用された楽器が使用されている曲がある。

mus_f_part3

Flowey戦の違ったバージョン。0:20から先はシーン遷移に使用されるため 通常のゲームプレイでは聞くことが出来ない。

mus_f_finale_1

"Finale"で使われなかった最初のパート。通常では代わりに"mus_f_finale_1_l"が再生されるため聴くことが出来ない。 これはFinaleの最初のパートが短いバージョンであり、"Photoshop Flowey"戦でやられた後にプレイヤーがゲームを再開した時に流れるという可能性が最も高い。

mus_piano

Played at the end of the Undertale demo if you kill Toriel in a neutral run, and appears as the last track of the soundtrack (titled "Good Night"), but isn't used in the final game.

mus_ruinspiano

それはゆっくりと荘重のピアノアレンジの「Ruins」。 Possibly replaced with "An Ending."

mus_menu5

There are seven variations on the Start Menu theme that switch out for each other as you befriend more characters, but only the first through fifth and the seventh are used in-game, leaving this sixth variant unused. Given various pre-release materials, it's likely that the fifth variation was supposed to be used for Mettaton, leaving this one for Alphys... except that even if you spare Mettaton, he runs out of batteries immediately after the fight and spends the rest of the game up to the True Pacifist final boss undergoing repairs in Alphys's lab, so the player (sadly?) has no opportunity to date him.

mus_birdsong's Hidden Loop

mus_birdsong is played when the bird carries you over the gap in Waterfall. However, the music only lasts one loop until it fades out. The file DOES loop properly, however, and a bit of the music at the end is cut off in normal gameplay.

未使用SFX

mus_sfx_a_swipe

A voice (presumably Mettaton) grunting.

mus_sfx_ahh

Flowey says "ahh".

mus_sfx_voice_triple

Flowey says "triple".

mus_sfx_voice_jafe

Flowey says "jafe".

Activity Level

Wait, we're categorizing this now?

Press Shift or X five times at the title screen to get this handy screen. Activity Level A is shown if you get a neutral ending. Activity Level B is shown if you complete a pacifist route. Activity Level C is shown if you fight Sans twice or kill him. If none of the requirements are met, "No Information" is shown instead.

未使用バトル

RG03とRG04

In the game's files with battle ID 76, there is a fully complete battle set up for two more Royal Guards, RG03 and RG04. RG03 and RG04 are mentioned by Undyne during a phone conversation as switching off with RG01 and RG02 on certain days. They were likely cut because this real-time daily event didn't work correctly. Their battle revolves around them being old friends who had a falling out, and the Pacifist solution is to get them to make up. The guards themselves are slightly incomplete, both using Aaron's defeated sprite as a placeholder.

未使用のテキスト

Alphys's crush

LOOLLLL IF YOU CAME TO THIS PART OF THE CODE TO SEE WHO I HAVE A CRUSH ON YOURE OUT OF LUCK

The script for Mettaton's quiz contains a comment, ostensibly meant to be an in-character quote from Alphys. Specifically, it's placed right after when Mettaton mentions that Alphys names programming variables after her crush, and thus appears to be a bit of an in-joke to people reading the game script.

Annoying Dog

The Annoying Dog item has battle abbreviations for normal ("Annoy Dog") and serious ("Dog") mode programmed. However, the Annoying Dog can't be put in a Dimensional Box and will disappear if the player leaves the room it is found in, so it can never be brought into battle. As such, these strings can't be seen without editing the game.

エラーメッセージ

Snowed Inn error

Error.

A generic error message, found among the strings for Snowdin's Snowed Inn.


Undyne chase error

* A rousing error.
* (Error.)

Among the strings used when Undyne collapses from heat exhaustion are these two error messages that appear to serve the same purpose.


HER OPINION OF YOU IS VERY... ERROR-Y.

エラー!!!
またね!

Among the strings used when Papyrus calls you about your clothing and Undyne's murderous intentions towards you is this error.


エラーランドの旅行

* Where will we go today?

         Error       Error

A developer's hell.

This is among the River Person's lines.


Alphys shipping error

* Error...

A generic error message located directly after Alphys asks the player if they think Toriel and Asgore will get back together. Guess not.


You've elected me in error

WOWi, Nice error.

Right after you're asked to be the ambassador to the humans is this error.


Flavor error

* それはエラーメッセージだ!
  はい        いえい      

If you reset your game, Toriel will guess your favorite pie flavor from the choice you made pre-reset. If this went wrong, this would probably be displayed.


ACT menu error

    * Error

At the very end of the ACT menu strings is this yet again generic error message.


Item menu error

* If you are reading this,&  I messed up somehow./%

The message that shows if you try to get info for a slot that's empty in your inventory.


Item description error

* Error!

This same generic message appears again at the end of the strings listing the item descriptions.


Papyrus call error

ERROR????

Among Papyrus's lines for when he talks about the spaghetti trap room with what he says depending upon if you say you ate it or left it is this error. This probably would have appeared if your choice could not be determined by the game.


Undyne call error

* Error?

Among Undyne's lines for when she talks about Monster Kid depending on whether you saved him, ran away and had Undyne save him, or otherwise ran away is this error. This probably would have appeared if your choice could not be determined by the game.

Ending call error

 [look left]  * i'll be honest.
  [winking]   * i have no idea what
                happened for you
                to get here.
 [look left]  * this is actually some
                sort of error-
                handling message.
[eyes closed] * so, if you're getting
                this ending...
 [look left]  * tell whoever made the
                game, okay?
  [winking]   * they'll fix it, or
                if it's a novel
                situation...
 [look left]  * they might even add
                another ending to
                the game.
[eyes closed] * chances are, though...
  [no eyes]   * you're just a dirty
                hacker, aren't you?
 [look left]  * yeah, get outta here.

Dialogue spoken by the character Sans for an ending meant to function as an error handler if none of the qualifications for any other endings are met, which cannot be triggered during normal gameplay. The actual script data contains control codes to change Sans's expression, represented here by bracketed text.

The music track "Dogsong" is played while Sans is speaking.


(Source: YouTube: Undertale "dirty hacker" ending)


Gyftrot error

Error!!

This generic error that you've seen a million times appears again among Gyftrot's strings.

This cactus is UNDER CONSTRUCTION
This article is a work in progress.
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.
Notes: I got lazy after this, I'll describe the errors better later, and probably put all of these unused strings into subpages when I can.


Aaron error ;)

Flagrant 
error
; )


Mettaton quiz show error

ERROR?


8-legged error, ahuhuhu~

... that this is&an error message!?

Finally, a slightly interesting error message!

This appears after Muffet receives a telegram from the other spiders that changes depending on your spending choices.


Papyrus fight error

THIS IS AN ERROR
MESSAGE.
REALLY!!!


Flowey's Error

* Error

Flowey will display this message and soft-lock the game if you manage to get in his room before fighting Toriel.

Papyrus's puzzle error

Error, Pepibs.


Grievous error

* grievous error

Placed among the strings for the annoying dog absorbing the artifact and Sans's asking to hang out.


Mettaton fight error

* Error Baby


That error's a bomb!

* Error.
* Error,

These two generic errors are among the lines for the bomb-defusing minigame.


Burgerpants error

* I'm a goofy goober Yeah 
  this errorr. message.

The strangest error message so far is among Burgerpants's lines. It appears to be a reference to the 2004 film The SpongeBob SquarePants Movie.


Newspaper writer error

* Beautiful.
* An error message.


True Lab error

 error


Papyrus's toolshed

WHAT!?
THAT'S IMPOSSIBLE.

If you get into Papyrus's toolshed by manipulating save data, reading the note will result in this message.


Legendary Artifact

* (This will never happen.)

Normally, attempting to obtain the Legendary Artifact will cause a dog to appear in your inventory, which will then steal the Artifact when used or dropped. However, if you remove the dog from your inventory via debug mode or other means and interact with the Artifact again, you'll get the placeholder dialogue above.

Inaccessible Echo Flowers

* Error!

Interacting with any of the numerous inaccessible Echo Flowers in Waterfall will give this generic error message.

Unused pre-battle message

You shouldn't read this.

The battle encounter that involves Aaron and Woshua being freaked out by Napstablook's music is not supposed to show a "pre-battle" message.

Satisfaction

Undertale-satisfiedex.png
Monster seems satisfied.

Unknown. Will appear by pressing O + P in debug mode while fighting Mettaton EX, then sparing him.

Quiche Guilt

* Somewhere^1, a quiche's worst&  fear becomes reality./%%
* A quiche in another timeline./%%

Part of an unused set of scripts named "quicheguilt" that involves you standing still in the quiche room.

Horse Stable

Among the lines for the garbage dump and Napstablook's house, there are a few lines implying there was a horse stable somewhere in Waterfall.

* (It's a horse stable.)/
* (Do you want to go&  inside?)&         Yes         No \C
* (You jostle the door.)&* (It's locked.)/
* (Suddenly^1, from inside&  the [redacted], you hear a&/%%

Interestingly, we're hearing a noise from inside what is supposedly the horse stable, but for some reason, whatever it was is replaced with "[redacted]", and whatever it is that we hear at the end is just outright removed.

This dialogue seems to be triggered by a trash can in Napstablook's courtyard. Inspecting it if flag 92 (yet again unused) is less than 3 will cause the same figure from room 272 to appear inside the "stable", and say

* x/%%

in Wingdings.

Monster History Part 6

Unused monster history text that is the only outright confirmation of what "fallen down" monsters as discussed in Alphys's journals are.

(It's a book labelled Monster History Part 6.) Read it Do not
Unfortunately, monsters are not experienced with illness.
However, when monsters are about to expire of age, they lie down, immobile.
We call this state "Fallen Down."
A person who has Fallen Down will soon perish.

Mortal Enemy request

As this comes right after Napstablook's friend request in Hotland, it may have happened as a result of rejecting the request. In the final game, the friend request rejects itself regardless of your choice.

METTATON has sent you a Mortal Enemy request.
Congratulations! You are now Mortal Enemies with Mettaton.
COOLSKELETON95 has posted a comment on this change.
CONGRATULATIONS, YOU TWO! WISH YOU A LONG AND HORRIBLE RIVALRY.
You rejected the request.
METTATON has sent you an invitation to "Die."
RSVP? Respond Ignore

Bepis valley Granola Bars

Bepis valley Granola Bars

Found along the lines of the unused "Mortal Enemy request" text. Its purpose is unknown, but it could just be a humorous parody of Nature Valley brand granola bars.

Art Club Room

This message is shown if you read the sign in the art club room in Hotland (where the secret boss So Sorry can be found) on a genocide route. However, the entire second floor of Hotland is blocked off by a force field on a genocide route, making this impossible to see normally.

(Art club is cancelled!)

Slow-dance with Mettaton

Among the lines for Undertale the Musical are these lines, possibly indicating you were originally meant to dance with Mettaton:

(Hmmm? Getting creative?)
(Dance with me, darling.)
(Oh! The audience can feel#your passion!)
(Show the audience#your passion!)
(So close... How passionate...)
(... do you need some help?)
(... what ARE you doing?)
(Don't stop now!)
(Look at you, leaping around#the stage...)
(Can't keep your hands off, huh?)
(Is that how humans dance?)
(Humans are stranger#than I thought.)
(Oh! They're really#getting into it.)
(Moving so far...)
(Who can blame you?)
(Hmmm, I'll have to get used#to it...)
(Even better than#I thought...)
(So that's wha #it's like.)
(Dancing with... A human.)
(What a shame...)

TestMonster

"obj_testmonster" is an enemy called "TestMonster", an early version of Froggit which, despite appearing to be a simple dummied-out enemy, is actually a cleverly-hidden event trigger that, if encountered in Sans's room after befriending Muffet on your 255th playthrough or later, proves key to reviving Gaster and saving Asriel. Just kidding, it was used for testing.

It shares many of its battle dialogues with Froggit, but it has a number of extra lines buried in its code.

* You feel intimidated by the&strength of this adversary.^4 &* Just kidding.
* The enemy cooks a small&bowl of flies.
* You can't concentrate&over the sound of croaking.
* The battlefield is filled with the smell of mustard seed.
* You think hard about words&that rhyme with frog.^4 &* Log.^4 Dog.^4 Snog.^4 Pog?
* A frog can't lick its&wounds because its tongue is&just too stretchy.
* You say some raunchy&things to those frogs.&Jeeeez!/
* There's definitely some&sort of reaction./^
* What's your favorite color?& &    * Red           * Orange"
* Do robots dream of&electric sex?/^
* I hate programming this./^

Flowey's big boner

* Big boner down the lane^8 %%
* Big boner down the lane^4 %%

These two strings are located among the dialogue for the Photoshop Flowey boss fight and the hacked "Floweytale" intro sequence. It's unsure what they could have been used for, but they likely were never meant to be seen by the player.

True Lab Entry Number 17

ENTRY NUMBER 17
monsters' physical forms can't handle "determination" like humans' can.
with too much determination, our bodies begin to break down.
everyone's melted together...

Alphys' entry number 17 is skipped in the True Lab, but is found in the code. Alphys instead explains this at the end of the area. W.D. Gaster has his own entry 17, which can be seen in room_gaster.

Placeholder Screens

Two screens featuring the annoying dog are present in the game. These are used as "error handlers" in case something goes wrong, such as loading a corrupted save file or entering an invalid or otherwise inaccessible room.

The song "mus_dance_of_dog" is used on one of the error handler screens (the left one), at a random pitch. The other song is "mus_sigh_of_dog".

Unused Items

Oddities

Annoying Dog's Sale Price

The Annoying Dog can be sold for 999G and haggled up to 1251G (the highest sale price of any item in the game!), but as mentioned above, it will disappear if taken out of the room it spawns in, so this can never be seen on a normal playthrough.

Developer Oversights

Mettaton EX Battle Essay

Mettaton EX has an "essay" question where you can type in text and have him comment on it. Unfortunately, typing "x" or "z" ends the essay unless CTRL is held down, leaving some words (in most playthroughs) untypable. In the PlayStation 4 and PlayStation Vita versions of the game this oversight was corrected.

The following words can't be triggered:

  • sexy
  • foxy
  • tantaliz (covers both "tantalizing" and "tantalize")

Mettaton's House

Mettaton's bed, upper walls, and TV have collision, but it's impossible to get in that section of the room.

Naming the fallen Human

In the PlayStation 4 and PlayStation Vita versions of the game, entering in the name gaster will result in a crash, rather than the intended reset.

Version Differences

Windows OS X and Linux

In the Windows version, the monitor in Alphys's lab follows your movements. However, this is only a static image in the OS X version. The static image for the monitor is still in the Windows version's files, unused.

1.001 patch

Hmmm...
To do:
Hastily pulled from the Undertale wiki. Add anything that's somehow not on that page, and add detail to this stuff.
  • The loading splash screen from the demo was restored.
  • The Joystick Config menu was graphically updated.
  • A kill sprite was added for "Ice", which is encountered by stealing Ice Cap's hat. Previously, it mistakenly used a placeholder sprite of Aaron.
v1.0 v1.001
UNDERTALE-BlueAttack-Old.png UNDERTALE-BlueAttack-New.png
  • The color of blue attacks was adjusted somewhat, as the original, cyanish hue made it hard for red-green colorblind players to distinguish these attacks from white ones.
  • Some dialogue was updated to account for aborted genocide runs, such as the phone call in the invisible maze room, Papyrus's bone box during his date/hangout, and possibly more.
v1.0 v1.001
UNDERTALE-UndyneCutscene-Old.png UNDERTALE-UndyneCutscene-New.png
  • An oversight that would cause Papyrus to appear during the cutscene where Undyne first appears, even on routes where he was killed, was fixed.


UNDERTALE-PuzzleSolution.png
  • A visual solution was added to the piano puzzle for the benefit of hearing-impaired, tone-deaf, or just plain uncertain players.
  • Dialogue relating to the "Clam Girl" NPC in Waterfall was changed and added.
  • The grandpasemi.ogg sound effect was renamed to grandpatemi and repurposed for Temmie, if you refuse to give her Tem Flakes.
  • Various layout changes were made to attempt breaking the "Lab Skip" glitch. This didn't quite work.
v1.0 v1.001
UNDERTALE-AlphysLabBathroomSign-Old.png UNDERTALE-AlphysLabBathroomSign-New.png
  • The bathroom sign in Alphys' Lab was moved from the right side of the door to the left side in order to patch the bug described above.
  • New dialogue was added for Burgerpants involving the Nice Cream Man.
  • The advancement of Sans's pre-fight text was altered slightly. He now says the short version after you survive the opening attack three times, rather than after he is defeated once and the player reloads to fight him again.
(Upon closer examination, the holes in the fabric seem to be growing.)
(Might take a while for the dog to fix all of them.)
(Dogs aren't usually very good at knitting.)
(A crocheting dog is out of the question.)
  • Dialogue was added to the secret Annoying Dog room, elaborating further on the "patch" that is supposedly needed before the Dog can be fought.
  • As detailed above, the "don't spoil the game, dataminers" warnings were changed due to no longer being necessary.
  • The Gaster-related "fun" setting now works without having to manually edit the .ini file first.
  • The Check option in battle no longer shows the actual stats used by the game code, instead displaying arbitrary numbers or silly messages.
  • The original version of the game had a major oversight that would allow the player to achieve a True Pacifist ending while having a non-zero amount of EXP (by reloading after a Neutral route in which no monsters were slain, killing some monsters in the Core, and then going to pick up Undyne's letter).
  • The unusually large space between Asgore and Monster Kid on the final version of the menu screen was shortened.
  • A (presumably) debug feature that would cause Undyne and Alphys's kissing animation in the cutscene leading up to the Asriel fight to start early by pressing the space bar was removed.
  • Various graphical glitches and typos were fixed.

A "1.001v1" patch was later released. This is a Steam compatibility update. Only one thing has changed; entering "Gaster" as the fallen human's name will reset the game, just after typing it. In the previous version, it only does so if you confirm the name.

Linux patch

The Linux version of the game is identical to 1.001, but includes a bugfix where pressing Z while pressing Enter would not register the Z input.

PlayStation 4とPlayStation Vita

Full-Screen Froggit

In the Ruins, the Froggit that mentioned pressing "F4" to enter full-screen was replaced by a Froggit that mentions that the border can be changed in the settings menu on the main menu.

Tiny Ruins Froggit

PC Console
* (There's an ant-sized frog in a crack in the wall...)
* (It waves at you.)
* (There's a small crack in the wall here.)
* (There's a frog inside...)
* (Wait! There are two!)
* (You had a wonderful, exclusive experience...)
* (... that only someone who saw two frogs could feel.)

As a result of removing the mention of "four frogs in this room" by the previous Froggit, this dialogue was changed.

Menus

The ITEMS option appears grayed out on the menu if you do not have any items.

犬神社

A location, likely parodying the Kickstarter campaign, was added under Papyrus's sink. You can donate gold to it to have it decorated with various items. The price gradually increases every time you donate, however. Each time you donate, you get a PlayStation Trophy. This area has two new music tracks, the second being unlocked after donating six times. It uses instruments from Super Mario World.

If Papyrus isn't befriended, the donation box will appear in the trash area of Waterfall, however donating here will only give you the trophies.


Sans

Your HP is displayed in pink the entire fight, regardless of whether or not you are taking KARMA damage.
