Rovio is teasing the newest version of Angry Birds Seasons with this new video. Angry Birds Seasons is a seasonal version of the popular game that updates with new themed-levels several times throughout the year.

Halloween 2011′s version appears to be introducing new villains, and perhaps slightly different gameplay.

It was a dark and stormy night as the Angry Birds’ newest adventure begins. The murky woods has spine-chilling creatures lurking in the shadows, but that won’t stop the Angry Birds. As the birds continue deeper into the forest, a big surprise awaits them. What could it be? Stay tuned for more! Squawk!
