I made this for my son's 3rd birthday. The firetruck is iced in buttercream, and all of the decorations (ladders, windows, hubcaps, etc.) are made from royal icing. The wheels are rice cakes covered in royal icing. The rope is licorice. And the siren lights are made from red gummy worms. The house is made of graham crackers glued together with royal icing. I sprayed black spray coloring in spots to make the house look burned. It also fell apart while I was gluing it together, but I thought this added to the whole effect so I didn't bother to fix it.
