Acorn

The Acorn is an object that appears in Ice Age in a Nutshell. Scrat is usually holding it but most of the time he loses it and goes out to look for it.

The Acorn is first seen in Ice Age in a Nutshell episode 1 on top of a pillow when Scrat is looking for it. He grabs it but then Shira comes along and takes it away from him. Scrat takes it back and launches himself off the bed with it.

Scrat is seen holding the acorn in Ice Age in a Nutshell episode 3 when he is walking across the couch. Then he sees Manny and screams, and then throws himself off the couch.
