In the middle of the movie Ice Age: Continental Drift Peaches' mom asked Peaches to go to sleep. Then, she hung on the tree. This particular scene was quite strange and confused me pretty badly, because she's a mammoth, why did she hang on the tree like that?
Further, I've only watched the Ice Age3 and Ice Age4. Did I miss anything? Did they show any scene towards Peaches' mom's strange behavior in the previous parts?
