There are 4 people who are quite weird.

Brutus: A purple mean guy, usually a dog, bull dog, or a hippo.

Lucky: A dog wrapped up like a mummy. There is a cut in the wrap, which reveals his... creepy... yellow... glowing... eye!!!

Ribbot: A frog robot.

Sprocket: Like ribbot, except a chicken (I think) instead of a frog.
