"Start Menu," previously known as "Menu," is the 2nd track in the Undertale Soundtrack. It plays whenever the player is viewing a new file.

After the player views the True Pacifist Ending Credits and gains the option to do a True Reset, a slowed down version of this theme plays.[1]


There are seven variations of this track. The Mettaton variation does not play in-game, and only two of these variations are included in the official Undertale Soundtrack: "Start Menu," and "Menu (Full)." "Menu (Full)" plays at the end of a True Pacifist Route and before completing the game.

Every subsequent iteration of this track adds instrumentals directly related to how many characters the protagonist befriends.
