Banana Nose Maldonado is a green Whatnot Muppet who played the villain in the Bear on Patrol sketch in episode 505 of The Muppet Show. He has a banana for a nose. When asked how he got such a ridiculous name, he replied "My parents were Mr. and Mrs. Maldonado."
The character's name is a reference to Robert Anton Wilson's 1975 Illuminatus! trilogy, which features a mobster character named Don Federico "Banana Nose" Maldonado.
An illustrated version of the character made a brief cameo in issue #4 of Muppet Snow White.
