Angry Birds Seasons brings in its latest season since Easter, the summer. Google celebrated with a Doodle and Rovio celebrates with a month long, advent calendar style world with 30 new levels.

According to Tech2, there are no extra "like us on Facebook" levels this time. Each day, a new level will get unlocked. The setting is, of course, very summery and like a picnic. Each level opens with butterflies fluttering out and there are pig shaped clouds in the sky. The pigs are wearing sunglasses and sunflowers line the background. The colors are much richer than before. This world is called "Summer Pignic".

This new Angry Birds Seasons update is available for iOS already with Android to follow soon. As always, the update is free however, if you don't have the app already, it costs $0.99 (Rs. 44) from the iOS App Store and is free from the Android Market.
