The pigs send a HUGE pig (pushing him on a wheelbarrow) toward the nest. The birds seem defenseless against him. Until Terence arrives!
At first, there's a butterfly flying at the birds' hideout. It disturbs Red, who is taking a rest on his folding seat, and Bomb, who was busy eating ice cream. The Blues also lived there, but the butterfly didn't disturb them with what they're doing. Instead of a butterfly flying there, there's also a ground shaking where someone will appear. It's a Fat Pig. He sings every time while the Minion Pigs brought him with the use of a wheelbarrow because he can't walk to the hideout to steal and get the eggs on his own. Corporal Pig also joined the pigs to give commands to the Minion Pigs. Bomb was shocked of him and his ice cream spilled on the ground. Red was also shocked that they also shook The Eggs. Fat Pig laughs after he sings. The birds got angry at him, especially Red.
Red went to the Slingshot to hit the Fat Pig where he extended the elastic band of Slingshot and released after. He hit him, but he got stuck to him because Fat Pig's body is fluffy and soft. Afterwards, he sings again where he fired Red back to his hideout. It was painful for him.
Next were The Blues. Instead of using the Slingshot to hit him, they just ran to him to hit and fight them. Before they ran, they left their shades and caps. But Fat Pig can sniff them using his big nose. After he sniffs them, he released them back to their hideout with his nose. Bomb saw that The Blues will hit the ground hard so used himself as a cushion to soften the impact. He then became angry.
Next was Bomb. He used the Slingshot to blow up Fat Pig. He lights his fuse, but he fell onto the ground near to him when Fat Pig had a tennis racket, which caused Bomb's explosion to be on the ground.
Then, they walked over Bomb while the Birds, except Bomb, got angry at him as he continuously sings. But he bumped into Terence, the Big Brother Bird. They didn't notice him when he arrives. The birds were protected by Terence at his back. When the pigs saw him, Corporal said that they will push the wheelbarrow (where Fat Pig sat) on Terence to hit him and pass over him, but Terence is too strong, while Fat Pig is fluffy. They pushed the cart three times, but still the plan didn't work. Terence got angry at them when they did it, because he knew that they will steal the Eggs. He made Fat Pig roll and demolish Pig City down by using his weight to make the ground crack. When it cracked, the wheelbarrow's wheels are inserted such that it made the Fat Pig imbalanced. He rolled and the pigs ran, but they're hit by him and as he rolled down to the Pig City, he sings louder when he hits the King Pig's Palace. Before they rolled down to Pig City, Bomb's almost hit by them as he moves beside them.
As the credits roll, Fat Pig cries because their plan will not succeed.
