PokéMMO is having a Halloween event
>kids in costumes hiding all over Unova, win in a battle against them to get candies (they change place every 10 minutes, you don't get experience or money though)
>ghost Pokémon walking in the overworld in Unova, talk to them to start a battle. Might have higher IVs than usual and possibly special particles (they change place every 15 minutes)
>big pumpkin in Driftveil, give it 5 Spooky Candies to get a Goodie Bag (chance at getting a random event-related item)
>give it a Special Candy to battle against the boss, Pumpking
>all battles are scaled according to your level
It's fun, but only in Unova. If anyone wants to play some PokéMMO (whether you're from pmmog/FUG or not) this would be a good time. Event lasts until the 5th of November
