Oh My...

"Oh My..." is the 67th track in the Undertale Soundtrack. It plays when Mettaton's switch has been flipped, before turning into Mettaton EX.

Trivia

 * It is reminiscent of the intro to "Killed by BR8K Spider​!​!​!​!​!​!​!​!," another track by Toby Fox, in Homestuck's AlterniaBound album which was then used in [S[A6I3] MINISTRIFE!!!].
 * The song is called 'mus_mettaton_pretransform' in the games files.
