On Christmas Eve, Fred Flintstone and Barney Rubble save Christmas for children all over the world by taking Santa’s place temporarily when he sprains his ankle on Fred’s roof delivering presents at the Flintstones’ house. Santa teaches them all they need to know and they do a great job, but Fred is late for a Christmas party hosted by his boss, Mr. Slate, and he could lose his job.
Note: This special can conflict with the Flintstones episode "Christmas Flintstone", which was created before this one. At the end of the Flintstones episode, Fred believes in Santa Claus, and specifically says that no one can tell him there is no Santa Claus. At the beginning of this special, he doesn’t believe in Santa Claus and Fred doesn’t believe Barney until he sees it for himself.
