The Transformation begins

Here's the challenge: Transform an ordinary sheet cake into a super-cool Transformers cake. So far, I've got the chocolate transfer done-

The plan is to put that on top of the sheet cake (similar to the Mickey cake), and embellish it as necessary. Colby likes the idea of actual Transformers toys on the cake, which I don't much care for. It is *his* cake, though, so I'm sure there will be toys on it somewhere. I'll post more pics when I have the finished product.
