Piglantis

Piglantis is the twelfth season in Angry Birds Seasons. It was revealed via GameCenter and announced on AngryBirdsNest.com. Speculation suggests that the theme is going to be somewhat familiar Surf and Turf, or nautical with Atlantis in the background.

Trivia

 * This episode name is a pun on the lost city 'Atlantis', which sank many centuries ago.
 * This episode may be the second Summer based episode (see Summer Pignic).
