Luca

In the summer circa 1959,[12] timid sea monster child Luca Paguro herds goatfish off the coast of the Italian town of Portorosso. One day, Luca meets Alberto Scorfano, a fellow sea monster kid living alone in an abandoned lighthouse. Alberto demonstrates how sea monsters can turn into humans, as long as they stay dry. Luca begins sneaking out to meet Alberto against his parents' order to stay away from the surface, fearing that he might be hunted by humans. The boys quickly become friends, wishing to own a Vespa and travel around the world. Upon discovering Luca's actions, his parents decide to send him to live in the deep with his uncle Ugo. In retaliation, Luca runs away from home and hides in Portorosso with Alberto. The boys run afoul of Ercole Visconti, the local bully and five-time champion of the Portorosso Cup, a triathlon of swimming, pasta-eating, and biking. When Ercole tries to soak Luca in a fountain, Giulia Marcovaldo, a young girl, stops him. In hopes of winning the money needed for a Vespa, the boys team up with Giulia for the triathlon.
