Examples of tushes in Ice Age
Even though Ice Age is PG, it shows several tushes, male and female characters.
In Ice Age, Sid falls down a hill and when he lands, you can see his tush. In a deleted scene of Ice Age, Sid is kicked in the groin by Rachel, then she turns around and waves her tail in his face, you can see her tush when she dose it, and when Jennifer and Rachel are walking away, their tushes can be seen shaking, while they are walking.
In Ice Age: The Meltdown, you can see Sid's tush when he is hanging in the vine, while he is going around Diego.
In Ice Age: Dawn of the Dinosaurs, at the start, Scratte is shown shaking her tush, and Scrat just stares at it. Later in the movie, when Scratte is choking Scrat, you can plainly see her tush. Later on, Egbert is shown scratching his tush before he runs off with his family. At the end of the movie, Scratte is organizing flowers and she is shown from tush view. In the end credits, when Sid and the baby dinos are dancing, Shelly has her tush pressed against Yoko's tush, and when gets out of the way she is shown shaking, then she gets a surpirised look on her face and goes running off with her brothers and Sid.
In Ice Age: A Mammoth Christmas, at the start, Ellie's tush almost shows, only showing her leg part. When young Peaches is having a snowball fight with Crash and Eddie, you can see her tush for a quick second when she jumps over them and before she plows them with a giant snowball from her trunk. You keep seeing Ellie and Peaches' tushes throughout the special.
In Cosmic Scrat-tastrophe, Scrat's tush can be seen after it slides on the control panels.
