Transformer Costume

My Son Kaden wanted to be a transformer for halloween and not just the reg. transformer he wanted to be able to transform, So after thinking about how to do this I came up with an idea, I placed an add on craigslist for a kids battery operated car I just needed the shell of one, I ended up getting a pink barbie doll car , and I bought some black and yellow spray paint in which I used to paint the car to look look like the bumble bee transformer car, I then cut the car into sections and made a hinge so the front of the car could fold over. I then added a string of halloween battery operated lights around the bottom of the car and filled in where the head lights would go with spray foam and added head lights using broken light bulb casing and christmas lights i cut off of the string and hooked to batteries and did the same for the tail light but using red bulbs. I also added a top using foam rubber and painted it along with plexi glass for the windows.
