Thank you everyone for your thoughts..
My bf and I created it out of box and made it so it would "transform"... Then I painted it blue and my mother (with her artistic ability) transformed.. (hehe) it from blue boxes into a semi. It did originally have two stacks but one fell off at school that day..
dugrant153.. I have it down to a science now.. so you supply the boxes to fit you body and I will tell you how to make it!!!!! LOL
It was alot of fun.. It was alittle heavy for him but he enjoyed it none the less... He really got into transforming as well... People would ask him what he was and he would say, "I'm Optimus Prime the transformer!!!, Want to see me transform?? " hehehe He usually got a second piece of candy as well for the act...
