I was in charge of making my nephews 7th birthday cake, which I of course love to do!! However, he wanted Sponge Bob, I really didn't want to make a Sponge Bob cake, so I convinced him to let me make this one. I had just seen the Ace of Cakes episode when Duff makes a gumball machine and I was itching to try it. I was really happy with the way it turned out. All the kids....and adults at the party thought it really was a gumball machine. So I would say it was a success!!!! Most important though was that my nephew absolutely loved it, and was glad I didn't let him have a Sponge Bob cake!!!! He and his cake were a hit with his friends from school!!! :-)
