Angry Birds Christmas in December, global flash mobs planned

The foul finches in Angry Birds are preparing to spread holiday cheer with Angry Birds Christmas, which should be available sometime in December. Pocketgamer took note of a Finnish site that posted images of the expansion which, if it follows the pricing of the previous holiday special, Angry Birds Halloween, should come crashing in at $.99. There has not been an official announcement made yet.

Developer Rovio has dubbed December 11 Angry Birds Day and has set up a website for happy players to meet up all around the world and form flash mobs. Further details regarding your mob's activities will arrive by email closer to the date -- don't worry, it will allegedly be suitable for all ages. Then again, it's probably wise to be cautious when the basis for a meet-up is bird flinging.
