It ain’t a typo – the episode is in fact entitled Summer Pignic, not Picnic. It’s about smashing pigs after all. So kick back, relax and enjoy the trailer. The video doesn’t reveal much apart from hinting “One bird, one mission: Save the eggs from the green pigs” (but you already knew that if you were a fan of the Angry Birds series).
From release notes on YouTube:
Get Ready for Angry Birds Seasons – Summer Pignic! The pesky pigs never break for holidays, and it’s up to you to save the Angry Birds’ eggs!
