Tahra is right: if you "View Source" for, say,
http://www.playmobil.de/on/demandware.store/Sites-DE-Site/de_DE/Product-Spareparts?pid=5139, near the bottom, you'll see a list of partnumbers, setnumbers, German names, and prices, like...
'30009552','5139','Grundfigur','2,70 €',
This, weirdly enough, does not correspond exactly to the parts illustrated in the Flash file: but if the part you click on in the Flash file ISN'T in this list, you'll get "Das gewünschte Ersatzteil ist leider momentan nicht verfügbar." (Not available.) There doesn't seem to be a way to order parts that appear in the source list but not in the Flash file, except the old-fashioned way.
I've written scripts to harvest this data and that available in the Flash files, so there's nothing here (except prices) that isn't in PlaymoDB, unless it's so new I haven't gotten to it yet. Most of the TO BE ASSIGNED parts and their German names come from here, though, so things do end up in limbo if I can't find out where to assign them, or haven't gotten around to adding the names and categories to parts.
Getting off topic! Basically, look in
Klicky-Body Parts,
Wearable-Hair,
Wearable-Beards, or
Wearable-Accessories for a reasonable number of mystery-figure parts, as well as the usual places for other accompanying regular parts. I have to assign them by deduction, though, so they're coming along slowly.
