American Baker in Germany

This is a cake my friend asked me for months before her 30th birthday. She asked me if I could make her a dragon cake. I was very nervous, but I told her I would try my best. After looking at lots of pictures of dragons, I realized there were many different kinds of dragons. Puff the magic dragon. Chinese New Year dragon. Dungeons and Dragons. How to Tame a Dragon. Lots of ways this cake could go. I asked my friend what kind of dragon, and she preferred the dungeons and dragons version. I told her it was hard to make a decent dragon out of cake, so I suggested making a castle out of cake and a dragon topper. She was happy with that. The cake itself should be chocolate. I know that she loves color, so I suggested doing rainbow colored buttercream, since chocolate cake isn't terribly colorful. She loved the idea. I started preparation about a week before her birthday. I baked the cake and made the dragon out of rice krispie treats. Real rice krispies are hard to find in Germany...
