Reginald J. Bottomfeeder is a talking fish who appears in Summer Vacation. Reginald travels with a shark and carries a book, which he uses to identify potential prey. He mistakes Jaya for a wounded fish, causing the shark to attempt to eat her, but she is rescued when Torg jumps into the water and knocks it (and himself) out. Reginald and the shark then go after Bun-bun, who Reginald identifies as a timid and harmless rabbit. When Bun-bun kills the shark, Reginald begins writing a complaint letter to the editor of the book, and is killed by Bun-bun after finishing.
