In DinoCity, you'll mount a dinosaur ride through six levels of prehistoric action. Watch out for the Neanderthal Rockys, though. They're out to make things tough for you, and they're trying to make the dinosaurs extinct! You must stop them at all costs. As you ride your dinosaur, you can knock out any of the Rockys by stepping on them or giving them a nice punch, but if the situation calls for it, you can dismount and fight them yourself. Each level ends with a tough boss.
