In order to find healing algae for the ailing bumpy-backed fish, Rainbow Fish volunteers to brave the dreaded Sea Monsters' Cave.

"Set in a beautiful seaside town on the Italian Riviera, Disney and Pixar's original feature film Luca is a coming-of-age story about one young boy experiencing an unforgettable summer filled with gelato, pasta and endless scooter rides. Luca shares these adventures with his newfound best friend, but all the fun is threatened by a deeply-held secret: they are sea monsters from another world just below the water's surface."--Amazon.
