Slide down through the layers of planet Earth, from mountaintops to molten core. Follow the Stickmen to trek down a glacier, descend into a canyon, and burrow down to the base of a volcano. On the way you'll see bears and snow leopards, geysers and giant machines, and tectonic plates grinding into each other. But don't be afraid—you're with the Stickmen, who'll show you just what makes Earth so amazing!
