Angry Birds Epic Trick or Treat Castle Dungeon is unlocked after passing Pumpkin Plateau level 1, which is only a few levels past the Mountain Pig Castle. It’s a tough castle, but definitely not one of the hardest. As usual, it’s a 5-wave battle. For help you can borrow on of your friends’ birds in addition to two of your own. Alternatively, you can use Piggy McCool as a default friend, or pay to use one of the Mighty Eagle’s more-elite birds.
