have you ever heard of a talking flower?
Premonition (/ pre.mə.ˈnɪʃ.n̩ /) is the 28th track in the Undertale Soundtrack. This elegant piano piece plays when Sans talks about certain suspicious flowers while the protagonist hangs out with him at Grillby's and in room water redacted. It plays at a lower speed in-game when compared to the speed in the game files, and plays at a different speed in the OST.
