During a boating voyage, Hoggish Greedly and Verminous Skumm land on the Galapagos Islands after Greedly accidentally knocks a toxin over Skumm's rats, causing them to grow and mutate form. They find some endangered Galapagos tortoise eggs, and plan to use them for food. The Planeteers, sent by Gaia to a museum with a camera-operated robot called JASON which can explore anywhere, see the two poaching and fly out to stop it. They have to defeat Greedly, Skumm, and the mutant rats, and even Captain Planet has to get past their supply of toxins in order to help.
