Scrat is a fictional rodent in the Ice Age franchise and the mascot of the now-defunct animation company Blue Sky Studios. In the 2002 film Ice Age plus its follow-up shorts and theatrical sequels, he is a saber-toothed, long-snouted rat-like squirrel with no dialogue who is obsessed with trying to collect and bury his acorn, putting himself in danger and usually losing his food in the process to his frustration. He additionally is a catalyst for major natural disasters that drastically alter the world around him and at times sets the stage for the main conflicts of the films. Scrat's storylines are mostly independent of those of other characters of "the Herd", though the two do intersect at times. While Scrat is a side character for the theatrical films that he appears in, he is the protagonist of other media such as certain shorts and his own miniseries Ice Age: Scrat Tales. In all of his appearances, his vocal effects were provided by the studio co-founder Chris Wedge, who also directed the first film.
