I carved this cake from 4-8" stacked rounds. The feet were also carved from pieces of cake. It was all covered in pink buttercream. The hooves, eyes and nose were made from fondant. The ears were made from a fondant/gumpaste mixture and I stuck skewers in them and inserted them in the cake. I also used a fondant/gumpaste mixture for the tail. I curled it around a pencil and let it dry overnight and stuck a wire in that. i don't like to insert wires directly into the cake, so i stuck a coffee stir into the cake and put the wire into that.
