Made this 3D cake for my friend's 4 year old son's birthday. This was my first 3D cake, first with fondant and first tiered cake, so I didn't want to risk transporting a 3+ tiered cake with a smaller base. I decided not to do the full body. Then I remembered R2 fell in the swamp when Luke went to visit Yoda and voila! the "swamp" is Cocoa Krispy Treats with green food coloring added to the melted marshmallows.
