Large sheet cake, halved and stacked. Iced with green buttercream. One football shaped cake pan used to make large side rocks. I halved the football cake, then shaped it into two large rocks/mountains iced in brown buttercream. Place cake trimmings between rocks and iced in blue buttercream for mountain stream. Also cut small area out of green cake for waterfall. Used ice cream cones for trees iced in green buttercream. Added small fondant stones. Lego items were placed atop the cake.
