YOU'RE BLUE NOW.
THAT'S MY ATTACK!
NYEH HEH HEH HEH HEH HEH HEH HEH HEH!!!

Papyrus after the blue SOUL mode is activated

Bonetrousle is the 24th track in the Undertale Soundtrack. An extended version of Nyeh Heh Heh! with added drums and violin, this song plays after Papyrus unleashes his blue attack.

Trivia[]

  • According to an interview with Toby Fox, this was one of the six songs originally composed for other projects. The other five were Fallen Down, Heartache, Nyeh Heh Heh!, Another Medium, and MEGALOVANIA.
    • Heartache, Nyeh Heh Heh!, and Bonetrousle were initially made for another RPG idea that never came to fruition. Said idea later turned out to be Deltarune, whose main battle theme was originally Bonetrousle,[1] but is now Rude Buster.
  • "Bonetrousle" is a made-up word. One of the notes Papyrus leaves to the protagonist after capturing them reads that Papyrus is "slightly bonetrousled" with their previous escape. The context suggests that the word might be synonymous with "worried," "flustered" or "annoyed."
    • "Bonetrousle" might also come from the verb "tousle" which means to make something untidy, or "tussle," which means a short, vigorous scuffle.
  • In the Genocide Route, the song is slowed down by 80% (8820Hz / 44100Hz = 0.2).
  • In the game trailer for Undertale (original and Switch release), in the segment where Bonetrousle is played, there is a segment of the theme that was never put into the final game (presuming the part all the way to the ending).
  • It has distinct similarities to Unfounded Revenge from Mother 3, such as the timing and the prelude before the majority of the song.
  • The OST version lacks a few background notes at the very end.
  • The Super Smash Bros. Ultimate version of MEGALOVANIA contains a few notes from this song.

  1. That game… I ended up repurposing a few of the songs from it for Undertale. For example, “Heartache” was originally called “Joker Battle” and “Bonetrousle” was originally the main battle theme. - Toby Fox, Indie World
