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!

Check out the video above for yourself, and tell us what you think we may see in the update in the comments!
