"Halloween in Skull Island Now through November 2nd, 2014, enjoy Halloween fun in Pirate101! Skull Island is filled with fun Halloween decor plus we we have new items in the Crown Shop and much more!"
The only problem is that the Halloween decorations have disappeared from Skull Island town and Avery's Court! Why remove them early (it is not yet Nov. 2, 2014)? Unless they've been stolen by someone who hates Halloween and doesn't like to see other people enjoying the day?
