Scrat

Scrat (also known as The Scrat and Squeak Attack) is an acorn-obsessed saber-toothed squirrel, one of the main characters in the Ice Age film series, and the main protagonist in the shorts, Gone Nutty, No Time For Nuts and Scrat's Continental Crack-up. He is voiced by Chris Wedge.

Scrat is commonly shown in scenes as a comic relief character, involving the gang, but never interacts with them, directly with a few exceptions. He appears in all four films, as well as his own short films, "Gone Nutty", "No Time For Nuts" and "Scrat's Continental Crack-up" and has also made a cameo appearance in Sid's short, "Surviving Sid". He usually has his own stories in the film, independent of the main plot, which are parallel with the journeys of the other main characters simply by chance, making the other characters meet him occasionally. Although not fully part of the gang, Scrat has proven to be enormously successful and has become a breakthrough character of the series.

Personality
Scrat is a squirrel who is totally obsessed with acorns, however he never manages to achieve one and instead cuases himself massive physical pain. Scrat is also responsible for several important occurrences in the Paleolithic ice age such as Pangea and the formation of Death Valley. Scrat's desire for acorns has proven to be very self-destructive, and to everyone around him, even destorying an entire civilisation of Scratlantis.
