Flowey introducing himself

Your Best Friend is the 3rd track in the Undertale Soundtrack and in the Undertale Demo OST. It plays during the protagonist's first encounter with Flowey. It consists of a simple two-channel chiptune melody and harmony.


  • During the tutorial with Flowey, dodging his "friendliness pellets" causes the track to slow down in 5% increments. After the third time, the track slows down and stops.
  • During and after an encounter that displays the message "But nobody came", when all the monsters in a region have been killed, a slow (one 13th of the speed or 0.(076923)x) and distorted version of this track's fifth and sixth bars play.[1] This slowed down version is known as mus_toomuch.ogg.
  • The track is in A-flat major, which Christian Schubart called the key of "the grave".[2]
  • Your Best Friend resembles "The F.U.N. Song" from SpongeBob SquarePants.[3]

    Key of the grave. Death, grave, putrefaction, judgment, eternity lie in its radius.
