Angry Birds are very different from all their relatives. That's what typical sparrows and pigeons usually do? That's right - they get lost in flocks and fly in garbage dumps in search of something interesting and edible. And like these feathered creatures do not differ aggressiveness, ruthlessness and craving for destructive actions. But the birds from the Angry Birds games series crazily want to arrange riots and pogroms. Victims of manic birds are many other forest animals, but most of all they got to bad boars. But now evil opponents are waiting for other opponents - an army of robots that appeared unknown from where and it is unclear why people walking around. They erect fortifications and prevent other animals from living.
