Ice Age: A Mammoth Christmas

Eight years after the events of the third film, Christmas is coming and Scrat eyes a beaver assembling a cache of foods, among them an acorn. Scrat sneaks in and takes the acorn, along with others he finds in the area set up as decorations. He ties a large stockpile of them on a piece of bark and tries to leave with them, but they break out and roll away, leaving him with nothing.
