Trick or Treat, originally called Angry Birds Halloween, is the first holiday-themed version of Angry Birds and Halloween-themed episode. It was released on October 21, 2010. It is based on the holiday of Halloween, and as such, features a dark, spooky environment. Pumpkins and jack-o'-lanterns appear as obstacles, the latter capable of giving 3000 points if destroyed, and the Pigs wear small pumpkin hats and sometimes are hidden inside a pumpkin. One Large Pig on Trick or Treat 3-15 appears wearing a ghost costume, swinging on a suspended platform.
NIGHT OF THE EGG SNATCHERS
I like dark and stormy nights. They remind me of my cave. But none was as terrifying as the Halloween when the birds found their nest empty. Had the eggs been grabbed by gruesome zombies, fearsome vampires or wicked witches? No, it was just the pigs — although Smooth Cheeks' face is just as freaky as any fright mask if you ask me!
