She is voiced by Emily Anderson.
In Ice Age: The Meltdown, Rose was first seen laying on chunk of ice. She woke up and saw Sid behind another chuck of ice, which made him look muscular. She was attracted to him; that is until he stepped out from behind the ice. When she saw what he really looked like, she said in disgust, "Ew." Then she got up from the ice and left.
Rose has yet to appear again, although it's presumed that she was on the boat too.
She is a bright red ground sloth with dark red hair on the back of head. She has a light yellow under belly and peach fingers and toes. She has a dark brown nose and bright pink lips.
