The Ember of the Cows

Operation "Kirjaimellisesti lopullinen pomo" or The Ember of the Cows as it is commonly known, is the final boss of Angry Birds: Out of Darkness. It was known as the last attempt to drive the Birds out of the castle. It failed and was destroyed at the battle of Coulavinlinna Castle.

Strategies
The Ember of the Cows is a very complicated boss, as it involves three phases.

The first phase involves the Ember slamming her arms down at a moving slingshot. While the slingshot moves it cannot be shot, so the slingshot has to be put down first and the arm that got stuck in the ground can be shot and immobilised. This must be done two times for each arm to completely destroy it.

The second phase involves the Ember attacking with her legs and kicking the corridors. The Birds and the slingshot must duck to avoid this attack. Once you get to the end of the hallway, use the slingshot to hit the gears on her chest to take out the legs.

The third phase involves the Ember standing in the middle of the castle and you must shoot at its' eyes to make it fall. Once it falls, the Birds celebrate and the leaders disappear.

Legacy
The Ember went down in history as the turning point for the rebellion, as this is where the rulers were sent into hiding, and the remaining Cows surrender, although there were pockets of Cows that still fought.

Trivia

 * The Ember had several designs, but there was two main designs based off of the character called Spinel from Steven Universe. This was done to mock the character, and the design.
 * Operation "Kirjaimellisesti lopullinen pomo" means "literally a final boss" in Finnish.
