Poached Eggs
Suddenly, King Pig and his minions steal the eggs. They attempt to cook and eat eggs. The birds injure Corporal Pig, Foreman Pig, and finally King Pig.

Mighty Hoax
In the second part of the plot, King Pig once again stole the eggs, but rather than simply fleeing, he placed cardboard cutout eggs in the birds' nest. The birds weren't fooled by this trick, and once again released their vengeance on the pigs for stealing the eggs the second time. There was also a cardboard cutout King Pig used to distract the birds. however, King Pig was behind it. In the end, the birds didn't defeat him. Instead, they just destroyed the cardboard cutouts.

Danger Above
The birds finally found out about the trick and the real King escaped to the jungle, a city, and the clouds. It turned out they flew out with balloons, stealing the eggs. The birds freed Hal, along their journey, befriended him, then he joined their flock. They get the eggs back.

The Big Setup
After the birds went back to the ground, King Pig and his minions kidnapped (or birdnapped) the entire flock to prevent the birds from defeating them and stole the eggs. Terence noticed this and decided to exact revenge on the pigs for kidnapping the other birds. In the meantime, the pigs attempted to reconstruct their forts. Quite anxious, Terence went to destroy the fortresses. He then sees Hal kidnapped again and frees him. Together, they freed the Flock. In the end, Terence and Hal put King Pig in a cage. Terence was given membership into the flock.

Golden Eggs
The birds examine multiple gold eggs they've recovered in their journeys defending the eggs. The pigs then try to steal it while the birds defeat them again.
