Sandy Fin

Sandy Fin lives in the Museum of Seaside Stories with the famous explorer Emile du Pont and their collection of treasures. Sandy and his best friend Lily are being taught the art of ocean exploration by Emile, aided by his ingenious inventions. When the museum's future is in peril, it is up to Sandy and Lily to save it. But then Albo Start arrives! Start plans to turn Portwhistle Bay into a Seaworld-style theme park named Splash Landing, locking up Portwhistle’s cherished marine life in tiny tanks.

Sandy Fin and his best friend Lily are enjoying life by the sea, after saving Portwhistle and its marine life from Albo Start's aquapark. Suddenly, odd things start to occur: an escaped convict is on the loose, curious mounds of sand appear on the beach. Strangest of all are reported sightings of the Phantom Diver – a figure of Portwhistle legend, long believed to be a figment of the most inventive imagination! Suspicious, Sandy and Lily dive, snoop and climb their way through the mystery towards the Phantom Diver's true identity.
