Blast-O-Cannon
From the Super Mario Wiki
Blast-O-Cannons are cannons that Wario jumps into and can blast out of in Wario Land: Shake It! Like pipes, Wario struggles for a short while to squeeze his fat buttocks to get inside. The player can tilt the Wii Remote to blast out of the cannon and break through blocks that would otherwise have been unbreakable, reach places he never could have before, and get to new ledges. Moreover, Wario can blast into another Blast-O-Cannon. Doing this can tend to be tricky, as cannons Wario shoots himself into can tend to move to make things harder for him.
