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 heavy cannonballs that fall tho the ground and 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 are also featured in Super Princess Peach under the name Cannon. The Calm Cannon, a sleeping variety, also appeared.

Trivia

 * The Nintendo Player's Guide description for the Kaboomba is accompanied by an image of one of the cannonballs instead of the enemy itself.
