“The Angry Birds Movie 4” (2026) continues the wildly chaotic, colorful, and comedic saga of Bird Island and Piggy Island, raising the stakes higher than ever before. The story begins with an uneasy peace between birds and pigs, a fragile truce held together mostly by Red’s constant vigilance and Leonard’s increasingly bizarre diplomatic initiatives. But when strange seismic disturbances begin shaking both islands, the residents suspect foul play—and the old tensions quickly resurface.

Red, still grappling with the pressures of being an unlikely hero, reluctantly teams up again with Chuck, Bomb, Silver, and Leonard to investigate the mysterious tremors. Their search leads them to an ancient map hidden beneath the ruins of the Mighty Eagle’s former lair, hinting at a long-forgotten third kingdom located far beyond the known islands. This revelation sparks both fear and excitement, as the group embarks on a journey to uncover who—or what—is causing the increasingly dangerous quakes.

Their voyage takes them into uncharted skies and through unpredictable weather, leading to some of the film’s most comedic and visually inventive sequences. When they finally reach the hidden kingdom, they encounter a new species of birds known as the Terrawings, an earth-dwelling tribe equipped with underground technology and an unwavering distrust of outsiders. The Terrawings’ leader, a stern but secretly sentimental bird named Granite, believes the quakes are a necessary warning to keep the islands separated forever.

As tensions rise, Red and Silver try to convince Granite that cooperation—not isolation—is the only way to protect all their homes. But Granite’s second-in-command, Shard, takes a far more aggressive stance, launching a plan to sink Bird Island and Piggy Island to force the Terrawings into total dominance. This pushes the heroes into a race against time, forcing birds and pigs to work together more closely than ever before.

The conflict escalates into a massive underground chase filled with slapstick mishaps, chaotic teamwork, and unexpected heroics from characters who previously preferred to avoid trouble at all costs. Chuck’s speed, Bomb’s unpredictable explosions, and Leonard’s oddball inventions all play a key role in turning the tide.

Ultimately, “The Angry Birds Movie 4” blends heartfelt moments with its signature humor, reminding audiences that unlikely friendships can reshape entire worlds. The film closes with a renewed alliance among all three kingdoms, proving that even the angriest birds can build a future where cooperation triumphs over conflict.
