Snowboy is busy saving the Polar Bear King when Greenbackboy approaches him with an idea for a game called KA-CHING -- a game that will make them rich. It's easy: all they need to do is cut down all of the trees in the forest and catch all of the fish in the ocean and trade it in for piles and piles of shiny KA-CHING. But if all the trees are gone, they won't be able to breathe. And what is a sea without fish?
