Aw, sweet thread! Childhood ponies make me feel warm and fuzzy, though I only had a few:
SS Windwhistler
Raincurl
And, apparently Sundance and McDonald's g2 Sundance, as I just found them recently in a really old bag (but I don't actually remember playing with them.)
Oh, and my sister had Glory so I'll add her by association, since I probably played with her (and I still have her sticker.)
