| 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! |
