Word World Cake

My sons best friend is turning 4 tomorrow and we stayed up tonight making him a World Word cake.  Its a super cute show from PBS Kids where everything is actually made up from the letters in their name or word.  I have been wanting to try a 3-D tree off the side of the cake like this, and am pleased with how this one turned out.  With some experimenting I want to try and make a more detailed one for the cake I am planning for next years cake show.
