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.
