The Heroes Act end up missing on Planet Scyria, which Icky immediately calls AUU Ark: Survival Evolved, and the Lodgers have to find them. Though they've each been scattered, and each have been surviving their own way. They've tamed the native prehistoric wildlife, and they're trying to find each other again. But even the Lodgers get separated with each of them. Thus they have to find whoever separated them and escape this planet.
