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 may take place underwater due to the fact that the name is a pun on Atlantis.
