The Karate kid goes underwater... Our hero, Pi, is a little fish who goes to live with his aunt on an exotic reef. Before long, he's madly in love with a pretty girl fish, but the local bully, a shark, also has the hots for her. So Pi decides to learn Kung-Fu so that he can take on the shark and win the girl, even though the shark is many times bigger than him. Reviewers have complained that this movie is a copycat of other similar-themed underwater animated films.
