The first time I was out shopping specifically for ponies I picked up Scoops and Peppermint Crunch at Value Village, then found a Princess Pony (Cant' remeber the name) at Goodwill.
Since then, on various outings, I've found... Skydancer, SS Northstar, Banana Surprise, baby Noddins, baby Cuddles, a really creepy, demented looking Sweet Stuff that I'm scared to be around, some random unicorn that I don't remember (In Glory's pose, I dislike that pose and I dislike rainbow ponies, so I forget.) Aaand today I just found Edgar the elephant.
Although I doubt I'll be keeping him, he's just not my thing.
Apart from that, I find g3's all the time, so I've built up a huuuge bait box. Anchors Away was probably my best G3 find, though.
