Wicked green pigs have invaded the birds nests and made them very, very angry. It’s now up to you to help them exact revenge! Pull back the birds in the slingshot and propel them into the enemy structures. Shatter glass, splinter through wood knock down concrete to get to the pigs. The level is complete when all of the pigs have been eliminated. Aim carefully however as you only have a limited number of birds. Each angry bird has different properties, be sure to take note of what they can do. The yellow birds for instance get a speed boost when you click and the blue birds split into three. Good luck!
