I'll probably move this to Scraps later. Since asked, here's the only part of my collection I've really focused on enough to photograph. If you can't tell, I like Gusty. She was my first pony ever. Then I lost her...I think I left her at a restaurant one day when I was in grade school. :< We went back to check, and the waitress remembered seeing her...but couldn't find it (I think someone else lied and took her...).

Then I discovered the internet in college.

Back row (left to right): US Gusty, So-Soft Gusty, Europe Gusty (looks the same as US but has flat purple maple leaves instead of sparkly glitter leaves), Italy Gusty, Argentina Gusty.
Front row (left to right): Brazil Baby Gusty, Baby Gusty with Beddy-Bye Eyes, Germany Baby Gusty with hideous hair chop and marker on face.

I only know of about...three more that I don't currently own. Also, I have a giant collection outside this, but I'm terrible at keeping inventory on them. Some of them are pretty weird...I used to make a point of stalking eBay to pick up the weirdo variants, like a princess pony with a glow-in-the-dark tail, or ponies mispackaged in the wrong boxes.

Also, yes, those are Breyers in the case behind the ponies.
