Go Fish! (DVD)

All his life, plucky parrotfish, Alex, has dreamed of being a superhero. He gets his chance when a mysterious flood of black goop erupts near his coral reef. As Alex and his pals--a sea horse, an eel and a blowfish--swim off to confront the menace and save their home, they face a sunken ship with hidden treasure, an abandoned airplane, angry sharks and an undersea volcano.
