I don't know if it is the long mane and tail or what, but it is behind her mouth :)

It's holding a stem, which is in her mouth. ;)

hello I hope you can help me? i used my shards to buy two(2) of the roses held in the mouth. they did not show up in my art editor, and they are not in my inventory either. I only have adult horses so I thought maybe i had mistakenly purchased the foal ones? but no, nothing is in my inventory.
