Wally Gator(1962)

Wally Gator is an anthropomorphic, happy-go-lucky alligator who wears a collar and a pork pie hat. Although his catchy theme song describes him as a "swingin' alligator of the swamp", his home is in the city zoo. Mr. Twiddle is the zookeeper who keeps a close watch on Wally because sometimes he escapes to check out what things are like in the outside world.
