I managed to catch three this morning, so I put them in my signature. Here's some of them, but I don't think it's showing them all, cause I don't see some of them in there:
There's a seasonal, a pumpkin dragon, and a shadow walker so far. Nothing that's new to THIS year that I've found yet, but there is an egg I've yet to catch, so that might be it.
