Our universe is shaped by an acorn-chasing squirrel. That is the major plot of ‘Ice Age: Collision Course’, which is also the prologue of the movie. Scrat, the prehistoric squirrel, falls into an ice-covered spacecraft, while searching for a perfect spot to safe-keep his precious acorn, and unintentionally launches the spacecraft, thus starting the Scrat-tastrophe. High up in space, Scrat’s series of mishaps cause the planets to collide to each other, positioning each planet to the current place, and creating the storm on Jupiter. Unfortunately, not only planets but also asteroids are hit by his spacecraft, causing them to move towards the earth.
Meanwhile on earth, Manny, Sid, Diego and the rest of the mammals are living their happy family
