The human baby in the 2002 film Ice Age is named Roshan. After his family is separated from him, Manny, Sid, and Diego undertake a journey to return him to his people.
Roshan’s father gives him to Manny and Sid after a saber-toothed attack near a waterfall. The trio then carries the baby across the prehistoric landscape, while Diego secretly struggles with his mission to reclaim him.
Roshan is often described simply as “the baby,” but the film’s official character name is Roshan. He does not become a recurring speaking character in the later feature films, which is why viewers may remember the role without recalling the name.
