When plucky penguin Pororo and his animal pals decide to be the world's greatest pirates, they discover a treasure map that brings them to a remote tropical island. There they meet marooned Captain Silver, who teaches them how to be good swashbucklers-but nasty Captain Dark shows up too, and wants the riches for himself. To claim the gold guarded by the fierce sea monster Kraken, they must solve a series of magical puzzles. But how can they escape the island that holds them all captive?
