The game takes place in the isolated Piggy Island. A flock of rare multi-colored birds, led by Red and containing the Blues (Jay, Jake and Jim), Chuck, Bomb and Matilda, guarded a nest containing three eggs. However, from the distance watched the Bad Piggies, led by the greedy King Pig Smooth Cheeks. These pigs have been relegated to eat grass, and King Pig, who, unlike his ancestors, has never eaten eggs and needs to keep that fact a secret, has had enough. Meanwhile, Red witnessed a mosquito touch one of the eggs. Furious, Red tried to fight the mosquito, but it got away (though in the cinematic trailer, he managed to defeat it). King Pig saw his chance, and, along with other high-ranking pigs Corporal Pig and Foreman Pig, stole the eggs while Red wasn't looking. Red and his comrades spotted the empty nest, and screamed in shock. Red, along with Bomb and Matilda, mourned the loss of the eggs, while the Blues spotted footprints leading to the pigs, whom Chuck had spotted. Using a slingshot, the birds slung themselves towards structures made by Foreman Pig, and managed to defeat all three elites and get their eggs back. Afterward, the multiple episodes show the pigs trying new ways to get the eggs. The birds meet more members of their species along the way (Hal and Terence), and the battle continues to places such as a forest, a desert, a mine, a beach, a laboratory, and more. After the birds take out King Pig in a laboratory, his comrade, Foreman Pig, starts to get more control over the plans. He steals the eggs while the birds are visiting a farm, and after the birds defeat him there, he enters a time machine and goes back to the Triassic period of the world. The birds destroy many structures based on prehistoric animals before the pigs are defeated for what was seemingly the last time. The birds celebrate their victory while the pigs ride dinosaurs.
