They are typically killed by directly hitting them with a bird, making their fortresses collapse, or hit by a TNT if they're close to it. In the Angry Birds games, the main objective is to kill all of the pigs in a level by firing birds at them with a slingshot. They built fortresses to prevent the birds from reaching the King Pig. The Minion Pigs are often seen stealing the birds' eggs, planning to cook and eat them. They have the appearance of green, limbless pigs (although they're able to hold objects), but they're depicted with limbs in the Angry Birds Movie. The Minion Pigs are the main antagonists of the Angry Birds series, who serve their leader, the King Pig.
