This was my son's 6th birthday cake. He's a fan of the Lego Rock Monster from Lego Power Miners. Two examples of the rock monsters are on the board. He requested a blue rock monster, standing up, with his mouth open, and his arm held up, holding a crystal, since rock monsters eat crystals, of course :). This is what he got. Mostly buttercream, with fondant accents. Arms are rice krispie treats covered in buttercream. Crystals are purchased rock candy. I will also upload a pic of his skeleton.
