Something is a brewin' for the Angry Birds this Halloween [Video]

The clip sees three tiny blue birds dressed up to trick-or-treat (likely the largely useless cluster birds) come across a spooky camp ground and a bucket with, well, something inside of it. Since the update is undoubtedly Halloween-themed, we're going to guess that this is an update to Angry Birds Seasons. And it almost seems as if a new bird or enemy will join the peeved off little birds.
