John Deere tractor cake

I made this cake for a friend's son's 8th birthday. He requested that HIS tractor be on the cake, complete with the hole in the front and the bungee cord holding the cover on (he had crashed it into the garage). LOL The tractor is my 1st attempt at sculpting something out of rice krispee treats. I still need lots of practice, but for my 1st attempt I didn't think it came out too bad.
