Ive done some list organization and countries are grouped now so its easier to read. Let me know if we are missing anyone.

Wow. So many more takaras popping up than i am aware of. I am out of the loop since I completed my takara collection I hope many more pop up for everyone.

wow super cool. Thanks for the pics.

OK and wasnt there a gingerbread with green eyes.. I remember that one as well

The birthday pony with yelliw streamers is not ooak. There was a MIB one for sale a while ago as well. The person who owns the loose version was twlling me about the MIB one she saw.

Just thinking to compile a list of current one of a kind nirvanas.
I know OOAK ponies are much rarer than they use to be since we have discovered more ponies with time Most of what is on the list are prototypes but there are still some OOAK africans, greeks, Thai and other country ponies out there too Plus there are a bunch of colombian and venny OOAKS out there too that I would love to record on the list. Here are a list of the ponies I know off the top of my head.
Let me know who I am missing.
