WC Moore plans on transforming Wannapoo into a 1950's styled theme park, based on Li'l Elvis and the Truckstoppers and re-naming the town Li'l Memphis. When WC promises to bring Goondianna Smith, Li'l Elvis' hero, to the official ceremony of the theme park, everyone is excited; everyone except Li'l Elvis and promises to get rid of W.C's influence on the town. Meanwhile, the Truckstoppers hear a rumour about an old Bog-Man who lives below Li'l Memphis. Li'l Elvis and his friends go off to find the mysterious creature while trying to ignore W.C's plans.
