Dave is an orange fish that wears a light blue top. He looks like Frank, except, unlike Frank, his eyes are on the top of his head. It is possible that he is a relative of Frank or that he's the same person because they look alike. In "Valentine's Day," he comes up to SpongeBob and thanks him for the flowers, much to the annoyance of Patrick. In "Patty Hype," he crawls into the Krusty Krab, claiming that he's had no food or drink in 3 days. SpongeBob immediately gives him a meal, but he leaves, saying that there's no theme in the Krusty Krab.
He is a relatively tall orange fish that usually wears a blue shirt.
