Chris transforms into a sloth to understand how it can hang for so long. The group's impression of sloths is that their lives are relaxing. While in his transformation, however, he is taken away by a harpy eagle and cannot avoid it because of the slow speed at which he is able to move. Chris briefly describes that sloths and harpy eagles have a predator-prey relationship.
Brielle teaches us about sloths. Sloths are slow moving animals and in the wild insects can live in their fur. Sloths may also fall asleep with food in their mouth and only go excrete excrements once a week.
All of the mammals begin their annual migration to avoid the winter. Sid the Sloth's family leaves without him, as they do every year, while Manny the Mammoth migrates in the opposite direction to avoid the warm weather.
