I believe that, counter-intuitively, Thailand fancy pants babies are the standard US release, so not especially valuable. I'm not sure how much fancy pants babies are going for at the minute though.
Yup this
Thailand Baby Fancy Pants are the normal US release of the set. There are China variations of 4 of them - those were released in Europe. And there are actually even variations within that last release.
These girls are the exception to the Nirvana rule.
Only they and Mountain Boys have been found manufactured from there - the latter are very very much Nirvana, the FP are just normal ponies.
Baby Bows is actually supposed to have pink hair
Has her mane faded as well as her tail? That will affect her price unfortunately.
