Trick or Treat

Trick or Treat, originally called "Angry Birds Halloween", is the first holiday-themed version of Angry Birds, released in October 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 Theme H3-15 appears wearing a ghost costume, swinging on a suspended platform.
