Sans.

Für den Charakter siehe Sans.

heheh... der alte furzkissen-in-der-hand-trick. er ist IMMER lustig.

- Sans' erste Worte, nachdem er sich zu erkennen gibt

"sans." ist das 15. Lied im Undertale-Soundtrack. Es spielt während heiteren Unterhaltungen mit Sans, in Grillby's, auf Napstablooks Schneckenfarm und während anderen unbeschwerten Momenten im Spiel.

Wenn man das Stück beschleunigt, scheint seine Melodie der Ursprung von "Song That Might Play When You Fight Sans" zu sein.

Trivia[]

Das Stück ist schon älter als Undertale an sich, da es bereits als Hintergrundmusik unter dem Namen "muscles.mp3" in einem Homestuck-Projekt im Oktober 2012 verwendet wurde.
Während dem Kickstarter-Video für Undertale wurde dieses Stück ebenfalls gespielt.
