Those paper dragons are giving me a headache. Very crane-like, but you'd never be able to fold one using the usual crane bodyplan, those only have 4 "limbs" to bend around and you can see at least 6 in those dragons. Maybe 7-8 for that horn on the dead to be possible, the opposite limb bent backwards into the front so you can unfold it into two points (beak and horn), but that'd mess with having a tail, not to mention the hump.
Seriously, how do you fold something like that? I bett there's got to be a way.
