Need help in identifying the purpose of mouthpieces.

At the tail end of last year I purchased this modded DDH-02 head that came with..... a lot of mouth pieces.  The person I bought it from purchased it off YJA.  This is my first modded head, and while I can guess what 1 or 2 of the other mouthpieces are, most of them I'm not sure of.  Would anybody have any ideas/guesses for them?  I mean, I really do love the fang mouth (though I think I need to fix it, again), but I'd like to know what everything else is for.

 

 

Wow. I mean, I guess the extra white bit could be a top row of non-fang teeth and then she can stick her tongue out of her mouth in about forty different ways? Tongue pointing up, tongue flopped out, etc. etc. I see heads with multiple tongue parts on Y!J a lot.

My best guess is that you have so many tongues because some of them fit the upper-fang teeth, some of them fit the non-fang tooth part, and maybe some of them fit no tooth part at all. What I'd try doing is removing as many mouth parts as I could and working them like a jigsaw puzzle - does anything specifically 'click' together? Maybe putting a discreet pencil dot on the underside of each piece as I identified it.
