Ice Bird

Ice Bird is a member of Red's flock who only appears in Angry Birds Space. He is an extraterrestrial companion to the Flock who helps them defeat the space pigs. He is the second original character to be introduced outside of the classic Angry Birds game.

Ice Bird appears exclusively to Angry Birds Space, but he makes cameos in Angry Birds Friends (in the Lotus F1 Tournament as a poster), Angry Birds Lotus F1 Team, Angry Birds Journey (as a statue) and in Boba's Delivery as a gag.

Appearance
Ice Bird has no feathers. Instead, his body is a cube shaped block of ice, that seemingly cannot melt. He has two rectangular icicles on his head and back, a long beak and brown eyebrows.

Personality
Ice Bird is a very mysterious character, and not much is known about his origins. He is very serious and hostile, and does not trust very easily. Despite this, he is very loyal to those close to him such as Red's flock as well as his egg.

Angry Birds Space
Ice Bird is first introduced when he falls out of a wormhole. He is initially hostile to the birds, out of the intention of protecting his eggsteroid. However, their first encounter is interrupted when King Pig's ship bursts through the wormhole and captures the eggsteroid, along with the flock's eggs. This event initiates Ice Bird to fly back into the wormhole, and the flock (consisting of Red, The Blues, Chuck, Bomb, and Terence) to follow them through the slingshot.

The flock encounter Ice Bird later on in the chapter Cold Cuts, where he is held in captivity by the pigs. Once freed, he convinces the Flock to help him in his quest to recover his eggsteroid. According to promotional material, he intends on saving his home planet from the Space Pigs, though this planet is never expanded upon nor introduced.

In gameplay, he debuts in Cold Cuts 2-3 but he becomes playable in Cold Cuts 2-4. He explodes when his ability is triggered causing the objects in his proximity to be frozen into an ice/glass-like material. This ability can be triggered by the player or automatically, moments after first impact, similar to Bomb. Ice Bird's explosion doesn't directly damage any regular blocks or pigs, but will make them brittle and easier to break. His ability will also set off any explosive objects in range, such as TNT. Ice Bird and the Lightning Birds (the Blues) are often paired due to their compatibility.

Ice Bird does not appear in the episodes Brass Hogs and Solar System.

Angry Birds Friends
He makes a cameo in the Lotus F1 Team Tournament on a poster in the background.

Angry Birds Lotus F1 Team
He makes a cameo in the game on a flag on the level selection menu.

Angry Birds Star Wars II
While he doesn’t appear in the game, Carbonite Han Solo has a similar power to him as he can freeze everything he touches. Unlike Ice Bird, he does not explode, though. He only slides across blocks, which causes them to freeze and reflects any laser contect with him.

Angry Birds Go!
There was a Twitter tweet which unveiled unknown concept that was discovered by a game designer named Liz Edwards. She also helped in the concepts of an Angry Birds game from there people asked if Ice Bird is in Angry Birds Go! but then she answered this: "I wish I knew! I don't have any information I was only an intern there for 3 weeks" that possibly concludes that Ice Bird could not appear in the game.

Angry Birds Journey
He makes a cameo as a statue in the background of Ancient Ruins.

Boba's Delivery
He makes a cameo as a squeaky toy for a gag till he is replaced by the real Han Solo in carbonite.
