The smelly man is a weasel like character seen in Chowder Loses His Hat. No one knows if he has a name. What makes him so smelly is because he won a garbage eating compitition.
It was revealed that he was very stubborn when they judged him.
Stated before he's weasel like, he has a beard and a moustache, he is color red, and has a leaf growing out of his head.
