Have I Bitten Off More Than I Can...?

Choo Choo! A month ago I had never heard of Toby the tank engine, but when I was asked to create a birthday cake for a brother ( 4 years old) and sister (3 years old) I began my quest to learn as much as I could about him.  This cake has turned out to be a mammoth task, an engine with three train cars, each holding a gum paste Care Bear.  Half inch foam board creates the base/template for the cake, believe me cutting foam is not an easy task!  Pictures coming soon...
