It's Halloween, and the Extreme Dinosaurs are after the Raptors again. This time the Raptors are digging into a volcano to release lava and heat up the atmosphere. In their attempt to stop them, the Extreme Dinosaurs release a parasite that attacks and neutralizes the aggression center of the brain, which in turn infects them causing them to become nice. The Extreme Dinosaurs' friends must cure them from the parasite so that they can stop the latest Raptors' plan.
