Hanna-Barbera Fun-In #8

Two crooks use a kangaroo (Hoppy) to rob a jewelry store but lose the kangaroo. Geese gets a sprained wrist while helping to change a flat tire and ends up in the hospital where the gang get confused and think that he has been turned into a kangaroo (actually Hoppy) so they use him in their game. The crooks try to get the diamonds from him but are stopped when the gang finds out that the kangaroo is really a kangaroo and Geese is still Geese.
