I hit up 3 on my way home today before I lost stamina (funny how I can't walk as much as I could before major surgery 2 weeks ago, eh?) and only found packages with non-alien ponies in them, earth, pegasus and unicorns a-plenty, but no double-horned aliens. I'll be looking in one or two tomorrow, and can get to a few more this weekend. I haven't given up!
I also found about a dozen other fakies of various sizes and types, mimicking all generations with a wide variety of success (or lack thereof), and half a dozen official FiM products (no blind bags, but some mini-figs, some jewelry, some plushies, some sticker packs). Anyone want pics of the Great Dollarama Pony Scavenger Hunt tomorrow?
The only pic I took today was of these, which appeared to be erasers with comb-able manes and tails. Each stands about an inch tall.
