So we got to the funniest character in the Ice Age cartoon series, this Scrat squirrel character. Let’s quickly click on the link and colorize all the images presented.
Scrat is a saber-toothed squirrel who is obsessed with collecting acorns, constantly putting his life in danger to obtain and defend them. He has his own stories in the films which are mostly independent of those of the main characters, though the two do intersect at times.
In a special feature in the second film’s DVD, his name has been stated to be a mix of the words “squirrel” and “rat”, his species allegedly believed to have been a common ancestor of both. In the Ice Age DVD commentary, he is referred to as “The Scrat” by directors Chris Wedge and Carlos Saldanha.
Scrat is voiced in all Ice Age movies and short films by director Chris Wedge. He directly interacts with the story’s main characters on eight occasions, mostly with Sid. In the first film, he attacks Sid when the latter tries to eat his acorn, successfully regaining it. He later meets Manny, Sid, and Diego asking him where the baby’s family is and Scrat attempts to tell them about nearby saber-toothed tigers, but Diego kicks Scrat away before he could do so. At the end of the second film, after Scrat created a hole in the valley and released all the melted ice, later attacks Sid for saving his life (when he had already almost died and gone to paradise and was about to get a giant acorn). In the third film, Scrat is stepped on by Manny and falls onto Sid’s head while chasing his acorn. Next, he appears when Sid’s “children” are batting a ball around, the ball actually being Scrat. Also, when Scratte rips off his fur, he screams so loud the herd can hear him, causing Crash and Eddie to deem the place a “Jungle of Misery”. Lastly, while Diego is sleeping, he wakes up when he gets hit with Scrat’s acorn. In the fourth film, when Sid pries open a clam, he finds Scrat inside. Sid’s grandmother mistakes Scrat for a rat and continuously hits him with her cane until he falls into the ocean.
Scrat constantly hunts for his acorn either to bury it or eat it, but fate always gets in the way. He invariably ends up in humorous or painful situations: being struck by lightning, pursued by avalanches, and repeatedly knocked unconscious while fighting for his acorn. Yet he never gives up. Scrat generally loses, except when he defeats a school of piranhas and successfully “battles” Sid. – source
