The Flock's history starts when Bubbles and Hal were kidnapped and brought to All Terra.
Bubbles and Hal see many other birds in cages. These birds are quickly taken away by laughing pigs. Hal and Bubbles immediately break open the cage, beginning the events of Angry Birds: Bubbles. They were able to stop the Decipiger from destroying Bird Island and defeated King Cumulus. They were defeated by the Cows and lost Callahan, Gummi, and Hal. Holly, following Callahan's death, went to the Haunted Mansion which was where Callahan's house was, and met Callahan's spirit and almost went insane from this.
