The survival of the Angry Birds is at stake – and they need your help! Dish out revenge to those greedy pigs and bring the world of Angry Birds to life. Turn your favorite game into a hands-on and creative experience as you construct your very own Angry Birds level complete with a working launchers. Precariously pile up the bricks and items to build an entire scene – then launch either Red Bird or Matilda towards it to topple the structure and defeat all of the minion pigs, just like in the game! The K’NEX Angry Birds will provide hours of fun at home or with friends. You’ll also get a bunch of bricks and other parts to stack and a bonus golden egg – enough to construct and re-construct entire levels from Angry Birds. Add other K’NEX pieces or use your imagination to build more extensive levels out of anything and everything you can find! All parts of this set are compatible with other K’NEX Angry Birds Building Sets, so you can mix and match birds, launchers, piggies, and levels – collect all of the K’NEX Angry Birds and Angry Birds Space Building Sets to expand your stages and customize your play.
