This one requires a bit of explaining on how Undertale and Deltarune function.

Video showing the sound at both original speed and sped up: 4. If you’re close enough to it, a very slowed down version of “mus_smile” will play.

Specifically, when you’re near the bunker south of town. The second is, of all places, in Hometown during the epilogue. Any game music that was playing will stop, and instead “mus_smile” will play, and the narration says that the cell phone “doesn’t seem to be working”. The first is when you try to make a phone call while in the dark world. Interestingly, it appears in Deltarune not once, but twice. This piece of audio is titled “mus_smile” in the files. Speaking of Entry 17, You may have noticed the creepy “music” playing when it is being displayed. If you do this, the text will read, “VERY INTERESTING.” Of interest is a line of dialogue that only occurs when you delete 10 or more save files, then go to delete another one, then back out when asked if you want to “TRULY ERASE IT”. If you haven’t yet, the save menu will not only appear different, but the dialogue for copying and erasing save files will be different as well. If you don’t know, the main menu is different depending on if you’ve already cleared Chapter 1 once before, or if you haven’t cleared it yet. In addition, another possible reference to the line is in the save menu screen of Deltarune before you clear the game. It’s used in the tweets in the lead up to Deltarune to make a very clear callback to Entry 17. The phrase “VERY VERY INTERESTING” seems to be a… catchphrase? of Gaster’s. Translated from Wingdings into plain English, it reads: But in case you don’t know about it, Entry 17 is a section of text, in the form of a True Lab entry, written in Wingdings font, and only accessible by editing the game’s files. Undertale’s hidden “Entry Number 17” is one of the more well-known Gaster Things.

If you can’t tell, that’s exactly six characters of black “censored” boxes - the exact number of letters you need to spell “Gaster”.

This gives us a hint to who the speaker is - look at the display name. This is a very unique voice, so it’s extremely unlikely it would be anyone else. Gaster.įor those that don’t know, on October 30th, 2018, the day before Deltarune came out, the official Undertale Twitter changed its icon and display name, and tweeted a number of cryptic tweets, which we now know to be teasing Deltarune.Īs you can see, the tweets are clearly written in the same voice as the person in the intro. This post is a summary of all the evidence that the person speaking in the “vessel creation” portion of Deltarune, and by extension the Game Over sequence, is W.D.
