Buck, Crash, and Eddy try to keep the Lost World from being overtaken by dinosaurs, as they set out to find a place of their own. Buck is a one-eyed weasel who first appears in “Ice Age 3: Dawn of the Dinosaurs.” Buck lost his eye in a fight with a mother T-Rex, and ever since then, the two constantly have a bone to pick with each other — literally, since Buck fashioned a knife out of a tooth that he knocked from the T-Rex’s mouth.
