Ice Age Universe (Earth-8999)

The Ice Age Universe is a universe in the Multiverse without any life and only ice.

History
The Ice Age Universe was the second universe visited by Brian and Stewie Griffin. They became trapped in an icy block, and argued on how to escape. Stewie attempted to cheer Brian by saying he would play with him, and noticed this broke the ice. He kept praising Brian, until the dog's tail hit the Multiverse remote and they were able to teleport to another universe.
