Hey, Neon! I don't know the names on most of these- but the pink ones in the corner look like Ice Princesses, which is one of the few outfits that I care to own. Mostly because it's the only pony thing that starts with I, so I need a sample for the Alphabet Quilt. I don't have a price check, either, but if you still have it at the time of the September meet, I would be interested!
The log looks too realistic to be a G1 accessory- maybe it's G2? What is the date on it?
