Though the film is meant to take place at least after Ice Age: Dawn of the Dinosaurs (2009), Peaches, the daughter of Manny and Ellie, is noticeably absent even though she was born in said movie. Furthermore, if the film takes place after Ice Age: Collision Course (2016), the characters Shira and Brooke are also missing without any explanation or mention of them.
