Some large rhinos chase after Sid, intent on harming him. He then runs to Manny for safety, and the two rhinos then push Manny back toward the edge of a cliff. Manny then pushes them back and sends them flying through the air, but they come charging back at him. Manny then tosses both of them aside with his tusks, but Manny and Sid then fall off the edge (but are okay after landing on the downward slope).
As Sid, Diego and Manny walk across an ice field, various volcanic explosions suddenly go off around them, causing them to run for their lives as the ice and snow quickly melt, leaving them atop isolated, vertical ice formations that they must run and leap from one to the next (with lava below them). Sid and Manny make it, as does Diego, but the tiger then finds himself trying to hold onto the edge of the ledge. Manny then tries to creep out and save him, aware that his weight could cause the whole thing to fall into the lava below. He does save him just as the ice breaks away, but Manny is then starting to fall and he slips over the edge on a chunk of ice (we presume to his death). Volcanic forces, however, shoot him and the ice upward and away from danger where he lands quite hard on the ground (temporarily knocking him out, but he's okay).
In one scene Sid, Manny and Diego are walking through a cave and come across drawings of Manny's family being killed by hunters and flashbacks in style of the drawings.
The characters must run for their lives when they are "chased" by hundreds of sharp pieces of ice coming down like arrows.
