I made this cake for my son's birthday. I used a 14" and 9" round cake for the bottom two teirs. For Mario I used a ball pan for his head and a small 7" (I think) round for his body. I rounded the top for his shoulders. I used a picture as a template for the facial features. I made all the figures out of fondant. The head started to tilt. That was the only problem. This was my first attempt at something like this. I was quite pleased with the result. Thanks for all the great ideas on CC!
