Kasey the Kangaroo appears in episode 120 of The Animal Show. She showed Stinky and Jake about kangaroos and how to jump around and that when kangaroo's don't jump they do boxing with each other.
The puppet used for Kasey would later be used in assorted Sesame Street episodes, starting in Season 35. Her taxidermist eyes were replaced with plastic white ones for her appearance.
The puppet also appeared in the extended version of Muppets Most Wanted, during the musical number "I'll Get You What You Want (Cockatoo in Malibu)" and a backstage scene when Christoph Waltz is said to be Austrian, not Australian. Louise Gold performed her for the latter scene.
