I'd be scared for a second, wonder what the heck was going on.
Then I'd go back to Nuvema Town and play the Wii I have in my room. Maybe, by now, they've replaced it with a Wii-U. Who knows. :3
Or, I'd go around the region with my precious Pokemon battling random people. I don'thave a clear idea of what I'd do, really. ._.
