Spats (Experiment 397) is a small yellow squirrel-like creature with cat-like ears, orange markings on his back, small pointed antennae, orange spots on his forehead and two prongs on his tail. Designed to make people fight with each other. The cure for this is to stop and count to ten. Lilo decides to give Spats to the owner of a professional wrestling show, in hope that he can use Spats to make pro wrestlers fight more convincingly. He is seen in The Proud Family crossover episode.
