Leonard ”Lenny” Lino is the deuteragonist of Shark Tale. He is Don Lino's youngest son, Frankie's younger brother, and Oscar's best friend for life. Unlike typical sharks who are vicious meat eaters, Lenny is a gentle, gold-hearted vegetarian great white shark.
He is voiced by Jack Black, who later voiced Po from the Kung Fu Panda franchise and Bowser in The Super Mario Bros. Movie.
