Just thought of something...
As some people have succeeded ordering parts from Specials (no instructions so no parts-numbers included in a set) from their DS-service... and these Mystery Figures come disassembled in their packages,
theoretically it should be possible to....ORDER EVERY SINGLE PART FROM DS??
So not only a hat or a cuff, but also a wig, a head, a pair of arms or legs, etc....!? If one phones DS when in a bought Mystery Pack the legs of the figure are "missing", could you get/buy a spare pair and possibly get to know the part-number? That would be great if it would work.
