Chuckya

Chuckyas are larger, purple enemies similar to Bob-ombs in appearance with a yellow antenna leading to a red orb, purple arms, red hands, a grey point they use to balance and move, and a black plate on their back. Their design changes in Super Mario 64 DS to have grey arms and antenna, and boxing gloves as hands. Their behavior is similar to the unreleased Moto. They attack Mario by grabbing him and throwing them. To defeat them, you must pick them up from behind and throw them. They appear in Wet-Dry World, Tall, Tall Mountain, Rainbow Ride, the "Huge" portion of Tiny-Huge Island, and Super Mario 64 DS' Battle Fort. They patrol a small area, and usually appear where being thrown by them will be problematic. They make a whirring sound when moving, similar to Heave-Hos. To escape being thrown by them in the N64 version, you must spam A or push the control stick several times.

Enemy Discoloring
Main Article: Enemy Discoloring

An aesthetic instance of Enemy Discoloring has been documented that creates a black Chuckya that appears to be referencing the unused Motos enemy, which also has several resemblances to the Chuckya enemy, further backing up the theory that Chuckyas are a more modern version of the Motos enemy.

King Chuckya
In some personalized copies of Super Mario 64, some have reported a large black or red Chuckya that mainly appears in Lethal Lava Land can replace a Big Bully or some other mission, and can require more than one throw to defeat. This boss unofficially referred to as "King Chuckya" usually drops a power star, though in some instances simply functions as a mini-boss that can drop a red coin, blue coin or several regular coins. It is believed this boss is a replacement of the Motos enemy, or based off of an unused boss fight referenced in the files of the game.

Laugh
Some reports claim that after throwing the player, the Chuckya will reuse Big Bob-Omb's laughing voice clip. It is unknown if this is a glitch or an intentional personalized change.
