The pigs in the Angry Birds franchise are green.
Green pigs are the recurring opponents of the birds in the series. In the original puzzle game, they occupy structures made from materials such as wood, stone, and glass while the player launches birds at them with a slingshot. Their goal is commonly depicted as stealing the birds’ eggs.
The pigs are not all identical. The franchise includes recognizable characters such as King Pig, Foreman Pig, and Chef Pig, along with many ordinary pigs of different sizes and roles. Their rounded green appearance became one of the visual signatures of Angry Birds, just as the red bird and yellow bird became signature members of the flock.
The color can be confused with the birds’ own bright palette, especially because later games and films introduced many orange, blue, black, white, and pink birds. In the core premise, however, the pigs are the green antagonists. They also became the focus of the 2012 spin-off Bad Piggies, which shifted attention from attacking pig structures to constructing vehicles.
