Chuckya

Chuckyas are large purple creatures that resemble Bob-ombs and are found in the game Super Mario 64 and Super Mario 64 DS. They move around a small area, and if Mario gets too close, they pick him up and throw him in a random direction. To defeat a Chuckya, Mario must pick the creature up from behind and throw the Chuckya, causing the enemy to explode and release five Coins. Yoshi cannot defeat these enemies in Super Mario 64 DS. They are found in Wet-Dry World, Tall Tall Mountain, Rainbow Ride, Tiny-Huge Island (in the giant area), and Bowser in the Sky. In the remake they have wind-up keys on the back.

Trivia

 * Chuckya's name is derived from the phrase "chuck ya!".
