Cardboard Cutouts

Cardboard Cutouts Appeared at Mighty Hoax. At the opening cutscene of Mighty Hoax, King Pig was holding a cardboard cutout of himself and they left some cardboard cutout eggs at the birds nest. Then at the second cutscene the Birds break a king pig cutout. And then at the ending cutscene they broke another cardboard cutout and get their eggs back and King Pig hides on a cardboard cutout bush.

And also at Angry Birds Chrome, at Chrome Dimension, on the the right you see that King Pig is hiding at a Chrome Symbol cardboard cutout
