Which Ice Age film introduced the character Buck?

Ice Age: Dawn of the Dinosaurs introduced the character Buck.

Buck is an adventurous weasel living in the dinosaur-filled Lost World beneath the ice. He helps Manny’s group navigate the dangerous environment and leads the rescue mission for Sid.

Simon Pegg voices Buck in the English version. The character is defined by his energetic personality, survival skills, and knowledge of the dinosaurs around him. His one-eyed design and improvised equipment distinguish him from the other mammals in the series.

Buck later returns in The Ice Age Adventures of Buck Wild, a Disney+ film released in 2022. That later title focuses on Buck, Crash, and Eddie, but the character’s theatrical debut remains Dawn of the Dinosaurs.
