I asked my nephew, Matthew what he would like for his birthday treat. He said t...hat he wanted a train cake with steam coming out of it to say Happy birthday Matthew. I must have had a strange look on my face. He looked at me and said "What's the matter? Thats easy to do!" Thanks to Ambrat for the inspiration! P.S. My nephew just called to thank me for the most AWSOME b-day cake. It was just as he pictured it.
