The lagoon at Sea Devil Island is an idealistic place for a colony of fish to live and raise a family … peaceful and quiet. A little too quiet for young Jack Herron, who yearns to explore the world beyond his lagoon. But it is forbidden for junior fish to venture outside the lagoon. So when Jack stumbles across a secret passage to the outside world, he sneaks out and leads his three closest friends on an adventure of discovery. Unfortunately, they discover more than they bargain for. Caught in the wrong place at the wrong time, Jack is framed for a crime he did not commit and the whole colony suffers a terrible curse as a result. To lift the curse, Jack and his friends must set forth from their island prison and find the evidence to prove their innocence. But this will not be easy. Standing in their way is an evil squid intent on world domination and the gruesome Scourge stingray clan. Their only allies? A not so bright pelican called Dave, a hollowed out coconut and a whole lot of luck. Can Jack, Lilly, Alex and Jonesy find the missing heir in time to save their colony? Or will the devious Krillanger end up ruling the world with the Scourge. Buckle up me hearties, for the Coconut Rebellion is about to begin.
