The Collector's ponies were the first ever set in My Little Pony's history, with each pony being in the "collector's" pose.
Blossom Blue Belle Butterscotch Cotton Candy Minty Snuzzle
Blossom is a purple pony with flower cutiemarks. The one I have is specifically the concave foot variant. I recieved her in a lot of baity ponies, and she had stains all over her body and was missing a tail. The stains cleaned rather nicely after an oxiclean bath, and I rehaired her with "Blossom" from shimmerlocks. The shade of purple was noticeably different from her mane, so even though her mane was uncut, I ended up removing it and giving her a complete rehair just so her Tail and Mane colors would be be more unified.
Cotton Candy is a pink pony with small white circles for cutiemarks. She is my personal favorite of the Collector's Ponies (Though apparently this is not the most popular opinion lol). The specific Cotton Candy I have I got for 10 bucks along with a complete Pony Wear Outfit (The pink pajamas), and I remember being really happy with the price considering that she's great condition and needed no restorations.
Minty is a green pony with white hair and shamrocks for her cutiemark. This specific one is actually the 2007 Basic Fun reproduction, given to me by my boyfriend. He gave it to me because this one is based on the flat foot design and he was unhappy with how difficult it can be for the flat footed ponies to stand. She did not require any restoration work. Her hair is a little wavy since it had been braided for many many years.
Snuzzle is a gray pony with pink heart cutiemarks and pink hair. This specific one is the 2007 Basic Fun reproduction.
