I had 3 "catch 3 Swablu" quests at the beginning of the event, and have not seen a swablu since it started. I got rid of all three! Up 0 Down
I'm swimming in voltorbs and sandshrew, and it's not dependent upon weather. Not complaining, since both are super-rare here. Prior to this event I have caught <10 of either. Up 0 Down
