Con Man is a lavender fish with light purple fins. He wears a small brown and orange top hat at the top of his head. He wears a brown vest over his light tan dress shirt with a black tie. When he was pretending to be a injured man, he was wearing white wrapping and a nebulizer, acting as if couldn't walk. His color changed in "20,000 Patties Under the Sea."
In the episode, "Chocolate with Nuts," he cons, or scams SpongeBob and Patrick out of their money three times by selling SpongeBob and Patrick chocolate bags and pretending he was seriously injured.
