The bum is a light yellow fish who only appears in the episode "Mall Girl Pearl."
He is light yellow and has brown hair. He wears a black hat, faded blue jacket, white shirt, and dark brown pants.
When Beatrice and Pearl are going to Grandma's Apron, the bum appears sitting next to another broken and messy store. During the scene where Beatrice uses her "granny power," the bum is seen hiding in a box in fright.
