They are a large Bob-omb variant with round, purple bodies, a red antenna, and red hands.
Behavior
With their hands, Chuckyas grab Mario (or either Luigi, Yoshi, or Wario in Super Mario 64 DS) if he gets too close, and whilst the character is stuck in a Chuckya's grip, it spins them around for about a second and then throws the character in the direction it is facing.
Etymology
The name Chuckya is a combination of the words "chuck" and "ya" (an informal way of saying "you"), referring specifically to how they throw a character after grabbing them.
In Super Mario 64 / Super Mario 64 DS
Chuckyas are encountered in Wet-Dry World, Tall, Tall Mountain, the giant Tiny-Huge Island, and Bowser in the Sky. For Mario to defeat a Chuckya, he needs to go behind the Chuckya, pick it up and throw it. As a result, the Chuckya will detonate and will release five coins.
Glitches
In the original Super Mario 64, there are several glitches that can be performed using Chuckya.
When Chuckya is thrown, Mario is propelled backward a small distance. This momentum can be used to force Mario through walls.
Occasionally, when Chuckya is next to a wall, he may throw Mario directly into it, resulting in an instant death since Mario is out of bounds.
While Chuckya is in the air after being thrown, he still possesses the ability to lift/throw Mario. This glitch can be used to move Chuckya to lower levels, and also move him underwater.
If Chuckya is picked up in or held in water, he will be "light," meaning that Mario will be able to walk around at a moderate speed and jump while holding him. This is particularly useful in Wet-Dry World in order to perform the infinite coin glitch.
If Chuckya is grabbed right as he explodes (from being thrown), Mario will pick him up and he will die. This will result in Mario holding a fake Chuckya, which may then transform into other objects.
