Red, Chuck, Bomb, and Terrence are Angry Birds who don’t quite fit in with the other cheerful birds on Bird Island. When they meet in an anger-management class, things are bound to get out of hand! Meet the Angry Birds, a Level Two I Can Read book, is geared for kids who read on their own but still need a little help. The Angry Birds Movie, based on the international video game phenomenon, arrives in theaters spring 2016. With a star-studded cast that includes Jason Sudekis, Josh Gad, Maya Rudolph, and Peter Dinklage, this film will finally answer the question: why are the birds so angry?
