A threat stance is a state that pigs enter when they are about to attack on the next turn.
When a pig's attack countdown reaches 1, he/she will take a threat stance, in which he/she will turn to face the birds and give off an intimidating look. This effectively ensures that the pig's back will always face the rear end of the battlefield, making it difficult to land hits there. Pigs in threat stance will also have red marks on their heads so that the player can easily identify them and determine which pigs need to be taken out. Some birds can also deal major damage to pigs in this state with their Super Shot.
