This is a role-playing game in which players collect and train dinosaur-like creatures (i.e., Vivosaurs) for battle in a championship tournament. As players dig up fossils and progress through the storyline, they engage in turn-based combat against other Vivosaurs: a menu system is used to perform various attacks (e.g., bites, slashes, fire/ice/wind); damage is indicated by colorful light effects and a loss of hit points. During the course of the game, characters refer to Vivosaur “droppings” (e.g., Dropping Fossils), denoted by pink or blue coils, and make comical remarks (e.g., "And you'll be Sir Phinnius Stinkbottom!” and “I'm so excited I could puke!”).
