I make a lot of zombies for wedding cakes. A lot of them are simply zombies, and I get to decide the details. Many of them are designed to match specific people- most often the bridesmaids and groomsmen as zombies. One time, I even made the father of the bride as a zombie.
This couple had an idea that was completely new to me- they wanted to be fighting off their pet dogs as zombies. Altogether, I think they turned out pretty awesome.
