The goldfish is a minor character in Oobi.
The goldfish is one of Oobi's pets, only seen in a game segment after the "Petting Zoo!" episode. After playing a memory game, Oobi and Kako pretend to be goldfish by moving around in a fashion similar to how fish swim.
The goldfish is mostly orange. It has a small dorsal fin on his back and a larger tail fin. Its eyes are large and black.
The goldfish has appeared in one episode of Oobi: "Petting Zoo!"
