This cake actually took 4 9x13 cakes to make. I had a ton of left over scrap cake...that of course was great with a bowl of ice cream. The "dirt" is a shaved Hershey's bar and the jumps are marshmallows covered in chocolate icing. What was nice about making this cake is, I didn't have to worry about crumbs in the icing since it was covered up by the chocolate.
