Though raised in a gangster family, with the dreaded father's most feared sailors, Lenny did not grow as his family expected. He is not as fierce as his brother Frankie. In fact, he is not like a shark in general because Lenny is a vegetarian shark! Meanwhile, in a different sea area, there was Oscar the whale-cleaning mechanic who was upset and tired from his job. Oscar and Lenny met when Frankie (who was training Lenny) told Lenny to hunt and eat Oscars. However, Lenny who did not have the heart to finally release the Oscars, make Frankie angry and invaded the Oscar to give Lenny a lesson. Unfortunately, Frankie was killed by a ship anchor that fell suddenly. The guilty Lenny soon left, but the tragedy was exploited by Oscar as the turning point of his life, turning him from a loser into a winner. In the absence of a definite witness, Oscar eventually became famous for having 'managed to kill' a vicious shark. The film is filled by a spate of talented actors and actresses, such as Will Smith, Robert de Niro, Jack Black, Angelina Jolie, and Renée Zellweger. In addition, the film also made the Oscar nomination for Best Animation of the Year 2004
