Jay, Jake and Jim, collectively known as the Blues, are recurrent characters that appear in the Angry Birds series. These three hatchlings are brothers who hatched from the same egg, and the youngest members of the Angry Birds. Virtually identical to each other in both personality and appearance, the Blues are immature and mischievous due to their age, often playing pranks on their friends, but are surprisingly clever and capable in battle. The characters debuted in Poached Eggs in the original Angry Birds; in gameplay, they are some of the weakest birds but are excellent at breaking glass. They also possess the peculiar ability to merge into a single bird and split again in mid-air.
