White cake baked and shaped like a flop. Icing is buttercream spread as smooth as I could get it. Polka dots are green buttercream. On the cupcakes, it's reverse. On cake board, I spread some icing to adhere the grahm cracker crumbs to resemble sand, and the thongs are Sour Patch Straws. (White cake mix - boxed, and simple Wilton buttercream recipe).
