have you ever heard of a talking flower?


Premonition is the 28th track in the Undertale Soundtrack. This piano piece plays when Sans talks to the protagonist about Echo Flowers and Flowey when they are 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.


  • This track is similar to the beginning of Before the Story, a track that appears in the PlayStation 4 version of Undertale as well as the Deltarune OST, though due to the simplicity of both it's debatable whether this is intentional or coincidental.
  • The file name, mus_mysteriousroom2, implies that this track was first composed for Room 272 before it was repurposed for the interaction with Sans.
