Angry Birds 2 is a hack of Angry Birds 1.0.0 (for PC.)
Birds Changed From Angry BirdsEdit
The Green Bird is the original Red Bird from Angry Birds. Like the Red Bird from Angry Birds Space, he is wearing a mask, only shorter. Like the Bommerang Bird from the original Angry Birds, he has an orange beak, only shorter. Also the Green Bird has no spots.
Big Brother BirdEdit
The Big Brother Bird is orange in this game. He is POWERFUL, and he does a lot of damage to the pigs (which are now red.)
