Peaches is the mammoth family’s daughter in Ice Age: Collision Course.
Peaches is the child of Manny and Ellie and has grown into a young mammoth by the fifth film. She is preparing to marry Julian, while Manny struggles with the idea of his daughter becoming independent.
Her storyline gives Collision Course a family-focused counterpoint to the asteroid plot. Manny’s overprotectiveness creates tension between father and daughter, although the family ultimately works together during the crisis.
Peaches first appeared as a newborn at the conclusion of Ice Age: Dawn of the Dinosaurs. She is therefore not the same character as Ellie, her mother, or the human baby from the original film.
