Following several days adrift at sea, Sebastian makes it safely ashore a small island. But he's not alone. Soon after befriending a flock of strange florescent green pelicans, Sebastian is forced to seek shelter and safety inside a buried space ship. There he discovers that the strange birds are actually Dorrgroos, an alien species from another galaxy. The friendly Dorrgroos can morph into the forms of other living creatures. But so can the Zeppendulars; an evil species of alien that occupy the larger island across the lagoon.The feuding species of aliens have been stranded on the atoll following the crash of both of their space ships eons ago. The Zeppendulars have managed to uncover and repair their ship and are getting close to leaving with the only means to get back home. To make matters worse, the 'Zepps' have placed a cloak around the entire atoll that renders it invisible from the air or sea. The Dorrgroos survival, Sebastian's rescue and the future of the planet earth may all rest in Sebastian's ability to develop and execute a plan to hijack the Zeppendular's space ship.
