Here, Scrat the squirrel discovers a time machine buried in the ice near where he lives. He discovers that by hitting the machine in one spot, he instantly (and his favorite acorn) travels to a new time and era.
The story accelerates as it goes on, with Scrat getting into one disastrous situation after another quickly hitting the machine to get away. It's amazing how many places he travels in such a short cartoon but all of them are not only funny but beautifully drawn. As with Ice Age, the animation is absolutely spectacular.
I think there are just two "Scrat" cartoons, one accompanying the DVD of each Ice Age film, but I could watch hundreds of these. They are so well done, it's hard to describe. I agree with those who say this should have won an Oscar. I saw the winning one and this is superior, entertainment-wise.
