My son asked me to make him a Wall-E cake for his 7th birthday. It is a multi layered choc mud cake, with chomp chocolate bars for arms and the head is made from rice krispys. The wheels are a combination of cake, cookies, peppermint lollies and licorice. And the boot is made up of left over cake moulded into the shape of a boot. My son loved it, totally made the effort worth while..
