Scorponok (and Cannonball) were constructed wrong on all the toys. The purple side pieces (that look like a ladder) under those shoulder pads are on the wrong sides. So if you take out the two screws on the back of each and swap over the two parts, the shoulder pads will fold down further away from the head. (if you aren't preferring to have the shoulder pads pointed straight up)


(The problem with Cannonball is the thighs, which can't be swapped over without special tools to remove the pins.)
