Anger Management Pack

The Anger Management Pack was a downloadable content (DLC) pack for Angry Birds Trilogy, for Xbox-360, PS3, and 3DS. It is available to download on Xbox Live or PSN. It is un-available on 3DS. It contains 130 levels, from Season 2 (Ham 'O' Ween - Piglantis) from Angry Birds Seasons, and Birdday Party (first 15 levels) from Angry Birds. The original trilogy levels only had the levels from Poached Eggs to Mine and Dine, and all the Season 1 levels. This is the first time the Mighty Dragon can be used (if Mighty Eagle is unlocked) in the game. Right now, it is unavailable.

Trivia

 * This is the first time DLC was a part of the Angry Birds Series. (Unless updates count)
 * The Wii, Wii U, and PS Vita versions don't need DLC packs, as they are built in already.
 * This is the first time the Chrome Pigs are seen in any of the DLC episodes.
