All of the suggestions that you guys have sound good to me. All of the alternative names are nice additions. Especially your Equestrienne, Tiermann!

I'm not familiar with Animobil, but I assume we could put a link here to the final list so we can easily access it?
Animobil is Tiermann's website. It contains great resources for Playmobil animals and heraldries (amongst other cool things). It's awesome; I'd recommend checking it out.
Would you like me to host this at Animobil?
If so maybe it would be good to add actual photos of each with front, side and back shots? Should we include an exploded shot showing all the parts too?
I can put the pages together if someone else would care to supply images.
That's fine with me. I can give you all the stock images, but I don't have nearly close to all of the different figures (or a decent non-film camera). Depending on what you'd want to do, I don't see a problem with having the stock image, actual images from different angles, and an exploded parts view for each figure. The more, the better.
I think, for the names, we could maybe have a general name that we all mostly agree on for each figure and then a list of "alternative names" for each (if they each get a page or something on Animobil). Or, we could just have a list of names with no general or alternative differentiation.
Just as another option, I could create a thread with all of the full resolution images along with names and any other information for each figure. The only thing that can get tricky with that is editing it when new series become public. This could be as simple as adding more posts, but if people were to respond and cause discussion in the thread, it can get cluttered. I'm sure that a moderator could take care of that, but it would probably be easier if Tiermann set up a comprehensive database on Animobil. I don't think Sylvia would incorporate something like that here.
