- "Get inside the cave!"
- ―Manny to The Herd[src]
The Ice Cave was a cave formed by ice.
During a collision, The Herd sought-after a safe place to be. After running and almost being crushed by an asteroid, they rushed to this cave for safety. Not long later, Sid, a ground sloth tells the herd that it looks like it's over, before a asteroid comes near the entrance, causing smoke. Ellie, a mammoth, turns Sid around as he says "Except for that one."
The cave is made entirely out of ice. It is very dark and has enough space to fit the entire herd.
