Angry Birds Trilogy/Unused Content

Bubbles and "BomBom
Among the sprites for the Xbox 360/PS3 version, there are unused designs of two birds. The most noticeable one is Bubbles' early design, along with his inflated sprite, expressions. He is also colored in a darker orange with green polka-dots. It's also noticeable that he has less childish expressions, which is what leads to speculate that he was intended to be elder than his final version.

Also, there are sprites of what seems to be an unused bird along with a smaller version of the same sprite. The sprites are quite similar to Kombo Studio 's Bomb design. It's speculated by the community that the mysterious bird design belongs to an unused bird found through Angry Birds Seasons code. According to the unused code, their ability was split into three (similar to the Blues) and then explode when the clones collide with something. The bird has been nicknamed "BomBom", as the unused code refers its sprites as "BIRD_BOMBOM_1".
