Jumbo Josh appears to be a green, muscular giant creature, vaguely shaped like a quadruped with four stubby legs, two widening forearms ending with mitten-like fists, and a rather bulbous head. On his head, there are two bugged-out eyes and a mischevious tongue-less mouth shaped to a wide grin. he features green veiny skin, along with a sort of orange splatter on his left arm. He is suppose to act like a gorilla. Apparently even more than an actual adult male gorilla.
