William is a floating eyeball and minor character of The Amazing World of Gumball.
He is Miss Simian's personal snitch, and takes it upon himself to spy on her students.
Due to his being a snitch and having overall creepy demeanor, he doesn't have any friends that are classmates. But, he is a decent guy most of the time, showing honor and friendliness.
- He only speaks into Miss Simian's ear.
- He has powerful psionic abilities.
- In the uncut version of the Gumball promo, he watches Gumball trying to "save" Darwin from a tree along with Anton and Banana Joe.
- He may be based off of the Golden Snitch from Harry Potter, as he is a ball with wings, and "snitches" on his classmates.
- He actually uses his eye to express his actions.
- He first spoke in The Voice, and only Miss Simian can hear him. He does not know that nobody else can hear him when he is speaking.
