Austin is a purple kangaroo and a major character in The Backyardigans. Austin's speaking voice is provided by Jonah Bobo. His singing voice was provided by Thomas Sharkey for the first three seasons and by Nicholas Barasch for the final season.
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.)
