On my run-through in White, I hit the Celestial Tower. I had sent over an entire boatload of Goletts from Black, picked through them, found the one I liked the most and added it to my team. So I'm EV training my little Braver and run into an NPC with a Stoutland. "Hey, a few dozen Attack points!" I think. I've taken quite a few Herdiers down without problems, so I'm thinking this will be an easy match. Imagine my shock when this happened:
Stoutland used Ice Fang.
It's super effective!
...you know, I thought it was just the guys on the Battle Subway that would troll you. Apparently not.
