When Sid accidentally destroys Manny's heirloom Christmas rock and ends up on Santa's naughty list, he leads a hilarious quest to the North Pole to make things right and ends up making things much worse. Now it's up to Manny and his prehistoric posse to band together and save Christmas for the entire world.
It's night; crickets chirp outside an isolated farmhouse. A bright light from a spacecraft shines through a bedroom window and lifts a sleeping man. However, the light and the small alien controlling it from the ship are unable to pull the man through the window: first it's the glass that impedes them. The alien frets; its supervisor - large, laconic, and green - watches. As the human keeps sleeping, the alien's tries every lever. Just as it looks as if the alien abduction will succeed, something goes wrong. The supervisor steps in.
