Unnamed crocodile

"Unknown Male Alligator" is a background character seen many times since the early seasons.

His first major appearance was "The Law of the Jungle Gym" where he puts an apple core in a paper recycling bin and Rattles yells at him for doing so.

His first speaking role is in "Tales of Grotesquely Grim Bunny" where he says "Whoa! Sushi-Omni-Ooni-Ogie Ragju Rans! Awesome!"

He appears in the book, The Bionic Bunny Show, as a crew member of the show.

Physical appearance
Unknown Male Alligator is an anthropomorphic alligator that wears blue jeans and a light yellow shirt with a heart in a circle design on it. He has his signature yellow headphones on, presumably to listen to music. He also has a wristwatch on his right arm.

In the book, The Bionic Bunny Show, he wears a blue t-shirt. The heart design in the middle is surrounded by the name of the show I Love Lucy. His headphones are colored silver, and include a microphone piece.

He is noteworthily one of the few reptiles in the whole show.
