Hey all. I've had Skidz for quite some time now and he is Probobly teid with Nemmy Prime and Rodimus as my favorite Alt, but ever since I first got him something bothered me. For those of you who own Alt Skidz, or have vast knoledge of his workings, could you please tell me why the hinge on his back (the on that folds the car roof) swivels, and why his fists swing in? Is there some sort of alternate robot mode to him? Thanks in advance.
