Angry Birds Movie. Meet the Angry Birds (Level 2)

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?
