Summer Pignic

 is the sixth holiday themed Angry Birds episode, and as such, is available through Angry Birds Seasons. The setting is a field in the summer. The chapter was first announced on their Facebook page; and on June 20th, their Facebook profile picture announced the name. The episode was released at the beginning of the Summer Solstice on June 21st, 2011, and like Season's Greedings, each level is unlocked in an Advent-calendar fashion, and does not require the levels to be completed in order to access the others. This is the only episode to have space-themed levels, although there are only 2 (including one as a Golden Egg).
