1/2 sheet cake cut in 1/2, then one 1/2 cut in 1/2 from corner to corner. 6 cupcakes. The corner pcs make the ledges, cupcakes are the inside mound and volcano. Toys came from a $$ store. I just assembled and iced to make a dino world. The one is suspended by a wooden skewer I sprayed blue. Just bored a hole in the toys bottom. I got this idea from a kit I had seen from Bakery Craft I believe. It was soo cool!!!
