The Ice Age Adventures of Buck Wild continues the escapades of the possum brothers Crash and Eddie who set out to find a place of their own. Together with the one-eyed weasel, Buck Wild, they face the dinosaurs who inhabit the Lost World.

It's a jungle out there for Blu, Jewel and their three kids after they're hurtled from Rio de Janeiro to the wilds of the Amazon. As Blu tries to fit in, he goes beak-to-beak with the vengeful Nigel, and meets the most fearsome adversary of all: his father-in-law.
