Angry Birds Seasons lets you lob birds at pigs, while simultaneously celebrating international holidays.
The latest update, we'll admit, isn't much of a season. The legendary (and possibly mythical) sunken island of Atlantis is as much of a season as strawberries, kangaroos and triangles. But it's somewhat summery, so we'll let Rovio off.
In these 30 stages you'll get to play with water physics, as birds can dive into the ocean before shooting back out. This can be used to make sneaky submarine attacks on the pigs, and dislodge their structures from beneath.
