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.

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