yes his rotates and has the bend forward and backward movement the o-ring Joes were famous for
ok.... so after re-reading your explanation I think I can finally picture what you did. You used the chest piece of the alpine set up inside boba's chest to hold one end of the o-ring and then used the hips from another o-ring joe on the bottom and used the 0-ring to hold them together at that joint.... correct?
interesting method for sure.
and for your information SIMON, I had an o-ring joe growing up and he was my favorite action figure until my friend decided to strap him into a rubber band sling shot and shoot him into the wall, which broke the o-ring hook and destroyed the figure.......
