World 7: Bowser's Castle - Super Mario Advance 2: Super Mario World

"World 7: Bowser's Castle - Super Mario Advance 2: Super Mario World" is a high quality rip of "World 7: Bowser's Castle" from Super Mario Advance 2: Super Mario World.

Joke
The advertised track is recreated using pitch-shifted "Nerf This!" samples. This is more than likely a reference to how many people say the high bass note in the original track sounds like a fart, especially in the GBA version.
