Scooby Doobie Doo! Birthday cake!

This cake was a special request by a very good friend of mine's daughter and it was so much fun to design it myself! I did piece together a few different ideas that I'd seen, and I love the overall effect. Scooby Doo is of course made out of marshmallow fondant. The cake is vanilla with buttercream icing and white chocolate cream cheese filling. The collar/tag, the mini birthday cake and the balloon are also marshmallow fondant.
