Graduation Cake

I made this cake for my son's graduation. I have only a limit of time because I was trying to make a surprise for him. So, the hat look quite "wobly" because it wasn't really dry when I put it together. Then I put 3 teddies, one with graduation hat, sitting on the top of books and the other one is holding a big pencil. All teddies are dummies made from plastic. Well done my son! Congratulation!
