Green Pigs

The Pigs are the main antagonists of the game Angry Birds.

They are green pigs who appear as the nemeses of the birds. This is mainly because the pigs would constantly steal the birds' eggs, angering them. Throughout the levels of Angry Birds, the pigs can be seen standing on or near obstacles which the birds must knock down in order to kill them. Some pigs have ways (such as wearing helmets) to make it harder for the birds to defeat them.
