Put a red blanket over your horse, or get a big big box, paint it red, lay it horizontal and cut off the top long and the bottom long, then attach string to it that will go over your horses rump and shoulders, then you can paint on a silver ladder, and windows and hoses, then have your horse wear a fireman hat, you might have to cut out places for it's ears or something
