Kaboomba

A Kaboomba is a walking cannon enemy found in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, and Yoshi's New Island. They shoot cannonballs that explode after a few seconds. Kaboombas only appear in The Cave Of The Mystery Maze and Raphael The Raven's Castle. Stomping them lets the player ride on them, and eating them does nothing. An egg or ground pound disposes of them.

Kaboombas would go on to be featured in Super Princess Peach under the name "Cannon". The Calm Cannon, a sleeping variety of Kaboomba, also appeared.
