Joey Kangaroo

Joey, voiced by James Patrick Stuart, is a bad tempered kangaroo with an Australian accent that always refers to himself in the third person who loves beating up anyone who steps foot in his habitat, especially Skipper and Julien. He first appeared in the season one episode, "Assault and Batteries" and later on in "Cat's Cradle" when he tried to beat up Officer X but was badly hurt instead. He also appeared to have a big role in "Skorca!" He made several cameos where he isn't an antagonist. Though usually only a minor character in the series, Joey has had several episodes where he was the main antagonists. In the season two episode, "Kanga-Management", the Penguins accidentally destroy the Koala habitat, forcing Leonard to temporarily live with Joey until the pen is re-built, to both's dismay. Eventually, the two settle their differences and become friends, agreeing on their hatred for the penguins.
