i got him today, and u guys are right; he's great. However, even after folding the hands over the arms i STILL couldn't get the arms to lock. Eventually I just slid the hands off and it all locked in.

I dunno what I'm doing wrong. It seems to be the ankle joints that are causing the problems; They block the hands, and the small flaps that o over them dont lock down right either. But i can't see how to do it differently.
