I just stumbled on a Garden Wing Vivillon. Which is cool, because I've been seeing High Plains Wing Vivillon all this time. Still doesn't beat out the Giratina Egg I stumbled across.
A spooky Halloween eevee. Going to catch a few, curious to see if they evolve with their little creepy "bag" heads
I just caught a Hoopa! It's not very often I find Pokémon not in my collection these days, so that was a nice find
