Green pigs are fictional characters from the popular mobile game series called Angry Birds. They are depicted as cartoonish pigs that often wear crowns and are known for stealing the eggs of the Angry Birds. Their primary goal is to build structures to protect themselves from the birds' attacks. In the game, players use a slingshot to launch birds at the green pigs' fortifications. The green pigs come in various sizes and have different abilities, making them a fun and challenging target. The game's success has led to merchandise, animated series, and even a feature film centered around these green pigs and their rivalry with the birds.
