The Ice Bird is an extraterrestrial bird that when launched into any Wood or Rock structures will turn them into Ice on impact. The Ice Bird is particularly effective at taking out enemy pigs that are hiding inside a stone walled fort as they not only freeze the wall but anything behind it. A good strategy is to use the Ice Bird with the Blue Bird as the Blue Birds are strong against Ice and can smash anything the Ice Bird freezes.
The Terence Bird (morphed from Big Brother Bird) is a giant green bird with extreme cosmic desctructive power and is effective at smashing wooden, stone and ice walls. When launched in the middle of any structure the Terence Bird will easily topple it over.
The Blue Bird are exactly the same as in the original Angry Birds. They split into three when you launch them by tapping on them while they are in mid-air. The Blue Birds are particularly effective against Ice Structures and setting off chain reactions.
The Bomb Bird (morphed from Black Birds) can be launched anywhere you want and does massive damage using a heat shock wave. When the Bomb Bird has made impact tap the screen to make him explode. Bomb Birds are very effective if all your targets are in close proximity to each other.
The Lazer Bird (morphed from Yellow Birds) is similar to the Kamikaze bird from the original Angry Birds except you can now tap anywhere on the screen to create a purple target which the Lazer Bird will then aim at. They are easily able to turn corners in mid-air after being launched by swiping/touching the screen into the direction you want them to go.
Although the Red Bird is powerful in this game it does not have any special powers. Use the Red Bird to target the wooden weaker parts of structures that pigs hide behind when you start a level. Doing this will help the planetary gravity destabalise and bring down large structures.
