Dangan Mario

Dangan Mario (弾丸マリオ, Bullet Mario) is an original transform that Mario takes in Super Mario-kun volume 6.

While traversing Tubular, Balloon Mario comes across two Passin' Chucks that manage to pop him and making him fall straight in a pipe. Mario reemerges from the pipe, which is actually a sentient Pipe Cannon, with a Super Star and is shot at full speed against the Chucks, defeating him. Mario then bumps in a ? Block from which he gets a P-Balloon and finishes the level.
