Come inside it's fun inside!! This is the cake I made for my youngest son's 4th birthday. It was really kind of tricky. The mickey mouse head is made of rice krispie treats and covered in fondant, but they were still too heavy. I'll try styrofoam next time maybe. The slide was a bit difficult too, but it's made out of fondant, so I know why I ran into that problem. The characters were purchased from The Disney Store and just placed on the cake.
