Scrat, designed by Blue Sky Studios, is based on a mongoose, Ice Age and its sequel Ice Age:
He is one of the characters in the background of the melting movies.
When the character was acclaimed, his role in the Ice Age animation was extended and a place in the second movie has been given.
In both films, he shares the lead role of his scenes with an acorn and makes him laugh with all his misfortunes.
Blue Sky Studios created another short film about Scrat's acorn chase, called "Gone Nutty".
