Sorry, I don't have pictures, I had the toy when I was a very small child and I haven't seen it since I was 6 years old. Basically, it was a medium sized horse, bigger than My Little Pony's, and it had a star-shaped gem on its forehead which was purple. The horse itself was either light blue or a greenish-blue, and it may have been fuzzy, I don't remember that part exactly. The legs were similar to some MLPs where they just turn into smooth hooves at the bottom without distinction.
If anyone has ANY idea what the hell this thing was, please tell me; I've looked through countless pages of MLPs and I don't see anything that matches it.
