Mr. Banana Brain

Mr. Banana Brain was a banana-shaped doll that served as Quackerjack's "friend." The insane former toy mogul would often talk to Mr. Banana Brain, and employ (poor) ventriloquy skills to make Mr. Banana Brain "talk" back to him, or to others. The doll could be used as a weapon, as it could be rigged with explosives. Quackerjack used two versions of Mr. Banana Brain. The first resembled a conventional banana with arms, legs and Groucho Marx-esque glasses, nose and mustache. Later, this Mr. Banana Brain was replaced with a more stylized version with an overbite, the top of its head peeled open, and dressed in a shirt and shorts.
