Angry Birds; Red's ancient son

What if Red didn't live alone in his house on the beach? What if he had an adopted son he raised after finding an egg?

Just one thing... what is his son? Do birds have tails? Or sharp talons on their wings? Or teeth for that matter?

See what happens when this ancient breed of bird joins the acts of these foul tempered fowl as they try to get their eggs back from swine.
