This was a birthday cake for the son of a friend of mine.
The cake was chocolate, 2 layers baked in 13 x 9 inch pans and then "1 cut in 2 unequal pieces to make 'beach' sections."
Godzilla was made out of gum paste (I was going through a gum paste phase back then) and painted with food coloring and water. I used one of my friend's son's toys as the model.
The houses were all made of very small flat panels of royal icing - in different colors - piped onto parchment paper, allowed to dry, built, and then crushed.
So much fun!
The rest of the cake was decorated with royal icing.
If I remember correctly, it was a hit.
