Shark Tale is a 2004 computer animated film.
PROLOGUE: A shark is swimming around the open ocean, thus frightening a small worm hanging from a hook. The shark sees the worm and stops swimming, introducing himself as Lenny. Suddenly, another shark named Frankie swims over to remind Len, who secretly freed the worm, about their real errand.
Meanwhile, a very young fish named Oscar is showing off to his friends about living in open ocean, telling his friends about wishing to live on top of the reef at South Side.
One evening, he told his girlfriend Angie about his thoughts, but the next day, Oscar caused a true scandal, a new hope for his fellow fish, but a worry and anger towards the sharks; until the ocean began its real turn.
