MR. PAPAYOO AND THE GREEN WORLD

Steam and Cube are desperate. Their children, Khuno and Chione, have vanished. All they know is that their tracks have led to the mysterious Green Door, but not much is known about the world behind it. They turn to their old friend, Mr. Papayoo, for help. Together, the trio heads on a journey into the Green World, uncovering a Papayoo village ruled by Chief Aliiokaululau. They soon learn the truth about this world and the monster that plagues it-the Dinodragotor. The only way to search for their children further is to beat the monster.

Nothing is ever how it seems, however, and even after beating the Dinodragotor, they cannot find Khuno and Chione. The word in the Green World is that the children have gone through the Red Door-another mystery to be uncovered, further away than any of them has ever dared to go.
Returning to the Lava World to regroup, their mission takes a turn when a mysterious red Papayoo arrives. He is Prince Rock of the Sand World, seeking a superhero to confront a monster tormenting his own world. And the superhero is none other than Mr. Papayoo himself.

Prince Rock, Mr. Papayoo, Steam, and Cube join forces, with a common goal-to beat the monsters in the Sand World and find the missing children. But time is slipping away. Will they succeed before it's too late?
