Chainsaw cake

For my husband's birthday -not my idea I'm afraid -I've seen something similar before but can't remember where. I don't have time to do much decorating for his cake this week because of orders ...much easier to smash one up instead!! (It had to be green since it's the colour of his fave footie team Panathinaikos)
