Mus wawa - Undertale

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

Joke
The melody is changed to a scene from the Family Guy episode "No Chris Left Behind" where Stewie follows somebody while playing the tuba. At 0:09, there is a voice clip of Stewie saying "That'll be sixty dollars", from the same scene.
