which you can see in the “Ice Age 3” trailer, below – details the following:
The movie “Ice Age 3” begins amidst a blizzard. Scrat is trying to get through it, when he notices his acorn. During his struggles to reach it, he is engulfed in snow and frozen. He manages to pop open his eyes, using them to lean himself toward the acorn. He successfully pulls it out, releasing warm gasses from beneath the ice, which thaws Scrat. Feeling around with his foot, he discovers he has made a large hole in the ice, and falls through. After hitting a few trees, he slides down to the tip of a something – a deformed tree trunk? – losing his acorn. Just as he finishes his slide, Scrat comes face to face with a Tyrannosaurus rex.The T-Rex roars at Scrat and we next see Scrat inside the dinosaur’s mouth twitching his eyes.
