Please don't post in the FAQ. This isn't one of them. Every1 knows he runs around randomly. If you wanna find him fast use zeppelins and once you do find him and kill him (and his worms) - put a few farms or builders or wisps where he died, so when he respawns you'll get a 'our town is under attack' thing. When faced with two choices just simply flip a coin. Not because it settles the question for you, but because that one second it is in the air you suddenly know what you are hoping for.
