During the days of the ice age, Scrat took an acorn with him everywhere, hoping to find a place to store it for the winter. Scrat also went out looking for other acorns so as to further his storage, looking all over for acorns and nuts.
Scrat went on fixated with taking his acorn until he met another saber-tooth squirrel named Scratte, who Scrat fell for, forsaking his acorn for a time until he grew to miss it and returned to his acorn, leaving Scratte behind in a world of dinosaurs.
Further on in time, through a mistake, Scrat was responsible for the separation of the continents, which divided Pangaea, the singular landmass, into various continents. After this, Scrat found a paradise on Earth for himself: an island populated by advanced saber-tooth squirrels known as Scratlantis. After finding it, however, Scrat sunk it by mistake, stranding himself in a North American desert.
At some point in his future, Scrat was frozen in ice and survived the ice ages, some twenty thousand years later, washing up in a block of ice on a tropical beach. Scrat lost his acorn and found a coconut, which he treated the same as his acorn, though in storing it, Scrat started another cataclysm by mistake.
