As a baby, Princess Ocean is sent away from the North Pole by her mother to escape the tyranny of a magma dragon that rules over the volcano. She spends the next twelve years on a local island, where she meets a polar bear that can transform, names him Roly Poly, and chats with a pair of small fish. A run-in with pirates brings her together with Momo, an inventor, and the companions set out to subdue and defeat the magma dragon. The series is a 26-episode fantasy adventure for television.
