While Angry Birds Trilogy encompasses Angry Birds, Angry Birds Seasons, and Angry Birds Rio, some of the mobile levels didn't make the cut. Those are now available as DLC for an extra $5 (400 MSP).
The "Anger Management" DLC pack includes 130 levels from episodes like Ham 'O' Ween, Piglantis and more. It also introduces the orange bird, which can expand like a gigantic, feathery blowfish. He looks pretty uncomfortable in the trailer above, but in the life of a bird the brief flash of pain must make the conquest over pigs feel all the more satisfying.
