Angry Birds Go Crazy. The Angry Birds have gone mad. They have jumped from his slingshot and are crawling to defeat the pigs. We’ll have to try to reach the end and try to defeat the king and rid the world of those pesky pigs In this case we do not have to launch the Angry Birds using the wood slingshot, we have to drive our little Birds over the ground trying to defeat all our Piggies enemies and trying to reach every level as soon as possible. Use your skills to arrive the end of every level with your Angry Bird alive.
