Kleen Island is the largest island on Atlantos and is the home of the bactrosaurs and their terror bird friend Gastro, and is also the only island large enough for life to exist on it. Gastro and several others of his species crash-landed there and set up a partnership with the natives and their ruler, Queen Soapi. However, most of the terror birds were secretly working for Janice the hoof-maiden and broke the toilet pipes on the island, causing dung to enter the ocean and pollute it, upsetting the megalodon. The enraged sharks, with help from the evil terror birds, built fearsome weapons called tank-tanks and attacked Kleen Island. However, Janice and her terror birds had sabotaged the tanks, causing them to break down and threaten to roast the now helpless megs alive. Teggs, Arx, Gipsy,
