Angry Birds Trilogy/Unused Content

Unused Sprites
Bubbles and "BomBom"

Among the sprites for the Xbox 360/PS3 version, there are unused designs of two birds, the most noticeable one it's Bubbles' early design, along with his inflated sprite, expressions, coloured in in a darker orange with green polka-dots. It's also noticeable his less childish expressions, what leads to speculate 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 desing belongs to an unused bird found through Angry Birds Seasons code. Acording to the unused code, their ability was split into three (similarly to the Blues) and then explode when the clones collide with something. The birde bird has been nicknamed "BomBom", as the unused code refers it's sprites as "BIRD_BOMBOM_1".
