The monsters of the Monsters Inc. Laugh Floor were busy. They were pulling double duty having to do regular shows during the day, and the Christmas themed show for the December 11th Mickey's Very Merry Christmas Party at night.
They found it fun talking to humans, making up new versions of carols like Jingle Bells - and Sam and Ella would, of course, try and make up a version of a more complicated Carol like Good King Wenceslas and fail.
Everyone was full of the Christmas spirit.
Even if they weren't quite sure what that was.
They were monsters, after all.
