As the sun sets over another gorgeous day at la Playita Del Condado in Puerto Rico, Meli doesn't want to go home. She loves the ocean more than anything, and with only five minutes left at the beach, she knows exactly where her last stop should be: the tidal pools. They are small universes of their own teeming with critters and creatures of the ocean. While looking into the pools, she meets a crab, Jaiba, who takes her on a dreamlike underwater adventure, teaches her about the importance of shark conservation, and reveals Meli's ultimate destiny: to become the Mother of Sharks.
