During winter, the Raptors make plans to warm up Earth in order to make it more hospitable for the Raptors. They do this by making Mt. Cauldron (a dormant volcano near Fission City) erupt by firing a missile into it so that the heat from it can be trapped in Earth's atmosphere. After the Street Sharks and the Dino Vengers thwart that plan, the Raptors do what they did on Calderas 3 by using their computer to activate every dormant volcanoes on Earth. Now the Street Sharks and the Dino Vengers must prevent the Raptors from activating the dormant volcanoes on Earth.
