Eventually, as he tries to stomp it into the ground, he causes a large crack in the ground that extends for miles and miles and sets off a large avalanche. He barely escapes, but finds himself stepped on by a herd of prehistoric animals. The animals are trying to avoid the ice age by migrating south, except for Manfred, an agitated mammoth who is heading north. Sid, a clumsy Megalonyx sloth left behind by his family, decides to go on by himself and angers two Brontops by ruining their salad and is attack. Sid is soon saved by Manfred, who fights them off. Not wanting to be alone and unprotected, Sid follows Manfred.

Soto leads a raid on the human camp, during which Roshan's mother is separated from the rest and jumps down a waterfall when cornered by Soto's lieutenant, Diego. For his failure, Diego is sent to find and retrieve the baby. Sid and Manfred spot Roshan and his mother near the lake, having survived her plunge. The mother only has enough strength to trust her baby to Manfred before she disappears. After much persuasion by Sid, they decide to return Roshan but when they reach the human settlement, they find it deserted. They meet up with Diego, who convinces the pair to let him help by tracking the humans. The four travel on, with Diego secretly leading them to his pack for an ambush.
