For a 6-yr-old's birthday. His Dad said he wanted a cake with a shark on it. I got carried away. The shark head is RKT - first time for me. I need to work on getting it smoother, but I see the possibilities. The 'sand' is crushed vanilla wafers held in place (sort of) with buttercream. I got a lot of the undersea life ideas from CC. AGAIN, thank you all so much!!
