yep! my sparkleworks has one too. a lot of the earlier G3's came with one that matched them- early releases of rainbow dash, minty, butterscotch, kimono, etc. came with these charms and you can see more of them here
I think they were meant to be like the pony can wear them or the owner can. I think they’re pretty so I always had my ponys wear them I was a little disappointed when they stopped coming with them later on
