Angry Birds Danger Above Part 1

Another month has passed for the birds and so far they have not seen nor heard of the pigs since their last encounter. As a result they are all confident that the pigs will not make a third attempt to steal their eggs. However, Red is still wary about their egg's safety so he has decided to keep a close eye on them at all times. Then Bomb receives a letter from his clumsy, screwup brother Hal that not only informs him that Hal will be coming to the Island to live with the flock, but that the pigs are at it again and this time they have something new up their sleeves...
