The Barrel of Monkeys are a real-life toy by Milton Bradley seen in the Toy Story series. It consists of a colored barrel (Andy's is yellow) containing twelve red monkeys. The goal of the game is to pick up the most monkeys by creating a chain with their hooked arms.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
