What kind of giant creature could this bone have come from? That's a question for Mighty Eagle-the wisest bird they know.

Join the Angry Birds on their imaginary trip through time to discover the most awesome animals ever to roam this planet: the dinosaurs! But why do the Angry Birds feel such a special bond with the ancient beasts? Maybe Mighty Eagle knows the answer!
