The base is a 12 in round covered in fondant. On top is the half ball cake. I wanted to have the Mickey head be cake but that wasnt happening. So instead I went to the craft store and bought a Christmas ball that was plastic and opened up. I covered it with black gumpaste let it harden. I then cut a hole int the bottom and hot glued a large dowel to the bottom. Let it set. Stuck it in the club house. Filled it with M&M's and added the top! It was a huge hit!
