The picture below shows the basic construction. I used a skinny loaf, a small loaf, and one cupcake. I cut the small loaf into three pieces. I used my cake paint for the blue and gray but used frosting dye for the black, red, and yellow. I used cream cheese frosting (had cream cheese and butter, no shortening) and discovered that the cake paint did not work well on it and the cream cheese frosting was hard to spread out completely smooth. The cake paint might have worked better if I let the frosting dry out overnight, but I think straight buttercream just works better since it crusts more and faster. I used mini chocolate chips for the eyes and double stuff fudge oreos for the wheels.
