Austin

"Austin" appeared in many episodes, the character who appeared in the least episodes of The Backyardigans and also that nasty piano player Kelsi Nielsen. He is a purple kangaroo in the game All-Star Brawl (Beauties).

A timid, but fun-loving purple kangaroo who moved into the block during season one. Though generally shy during the course of the first season, Austin starts to come out of his shell, revealing a smart, friendly, and imaginative child. Although rarely appearing in the spotlight, he does take the role of the lead character in some episodes. Says Bogush: "Austin's usually the one pulling up the rear. He's kind of a get-along guy."

While usually a friendly character, Austin can act out his grumpy side every once in a while, such as in High Tea or The Magic Skateboard. Austin's roles usually start as heroic in the first season, like when he was a superhero along with Uniqua. He also plays the main hero in a robot on rampage in season four. As the seasons go on, his roles become a little more villainous: in The Action Elves Save Christmas Eve!, he serves as an antagonist along side Tyrone and also plays the main villain in Flower Power.
