Kaboomba

A Kaboomba is a walking cannon enemy found in Super Mario World 2: Yoshi's 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.

The name "Kaboomba" is a portmanteau of the words "Kaboom!" (onomatopoeia for an explosion) and Goomba. Due to the Kaboombas' lack of similarities with Goombas, though, the name "Kaboomba" may just be a form of "Kaboom!". The Kaboomka Fireworks Factory was named in a similar style.
