Mus whoopee - Undertale

"mus_whoopee - Undertale" is a high quality rip of "mus_whoopee" from Undertale.

Joke
This rip imitates the "Nerf This!" video, with Sans' voice standing in for D.Va's, Undertale 's damage sound standing in for the slap, and the advertised track standing in for the fart.

Trivia

 * This rip is very similar to "mus_mode - Undertale".
