The Ice Age Adventures of Buck Wild

Crash and Eddie, in their pursuit of perfecting a stunt, inadvertently trigger an avalanche. This accident results in the destruction of the gang's summer dwelling, prompting anger and concern from their friends.

Following the avalanche, Manny, Sid, Diego, and Ellie express their doubts about Crash and Eddie's survival abilities. This reaction fuels the possums’ determination to demonstrate their independence.

Under the cover of night, while the rest of the gang sleeps, Crash and Eddie sneak away from their temporary camp. They aim to prove they can survive on their own, embarking on an unintended adventure.

As dawn breaks, the gang notices the possums are missing and Ellie insists on searching for them. Meanwhile, Crash and Eddie stumble into the Lost World, a mysterious realm teeming with dinosaurs.

In the Lost World, Crash and Eddie reunite with their old ally Buck. Buck heroically saves them from a pack of raptors, highlighting his bravery and experience in this dangerous land.

Buck informs Crash and Eddie about Orson, a Protoceratops who seeks control over the Lost World. Having faced bullying in the past, Orson now embodies a survival-of-the-fittest ideology.

As Buck attempts to lead Crash and Eddie back home, they discover that their exit is blocked by a massive boulder placed by Orson. This seals their fate in the Lost World, forcing them to seek shelter.

While Buck shares his past experiences, the group’s hideout is discovered by raptors. They are saved by Zee, who uses a gas to incapacitate the predators, showcasing the power of teamwork.

Orson retaliates by attacking the watering hole where Buck and Zee are sheltering. As chaos ensues, Buck and Zee emphasize the need to evacuate the other animals for their safety.

Despite their past conflicts, Buck and Zee rally with Crash and Eddie to seek assistance from Momma, a fierce Tyrannosaurus. This alliance becomes crucial for facing Orson's menacing plans.

In a brave act of selflessness, Buck sacrifices himself, allowing the others to escape and regroup. His capture becomes a pivotal moment, igniting the resolve to rescue him.

Ellie, Manny, Sid, and Diego discover the entrance to the Lost World and join forces with Momma to rescue Buck. They plan to confront Orson and disrupt his oppressive regime.

During the intense confrontation, Buck attempts to reason with Orson, advocating for peace. However, Orson stubbornly dismisses these pleas, resulting in a showdown between their forces.

In a clever turn of events, Crash and Eddie manage to create flames that attract the raptors towards Orson instead of themselves. This ingenuity helps restore order to the Lost World.

After the battle, the gang realizes their misjudgment of Crash and Eddie and invites them to return home. However, the possums choose to stay in the Lost World with Buck and Zee, marking their growth.
