The Christmas tree isn't the only thing green in this new holiday classic. Shrek is back and trying to get into the spirit of the season. After promising Fiona and the kids a Christmas they'll remember, he is forced to take a crash course in the holiday. But just when he thinks he has everything for their quiet family Christmas just right, there is a knock at the door.

The King of Far Far Away has died and Shrek and Fiona are to become King & Queen. However, Shrek wants to return to his cozy swamp and live in peace and quiet, so when he finds out there is another heir to the throne, they set off to bring him back to rule the kingdom.

For their first day on the job as the new protectors of Metro City, Megamind and Minion are selling off the gadgets from their evil lair. But when one seemingly harmless "button" unleashes the gigantic robot MEGA-MEGAmind, the duo will have to resort to their old tricks to restore order.
