The 1992 short film "The Spirit of Christmas" is basically a South Park episode (with a slightly different animation style) packed into 4 minutes. The four boys accidentally create an evil snowman with tentacles who promptly kills one of them, then transforms into Santa and when the kids ask Santa for help, he kills the second. So the kids go see Jesus. And luckily, Jesus is not the evil snowman in disguise, but kills the villain.
This was the first time Trey Parker and Matt Stone entered the very long-living world of South Park. The show is at its 18th season now already and this short film here was made 5 years before everything started (and 7 years before the movie). The characters have quite a few differences compared to what they were in another short film by Parker/Stone also called "The Spirit of Christmas" from 1995 and the show later one. Kenny gets actually killed here, a running gag for a very long time in the show, but he has Cartman's outfit and the clothes are different in general. Also, you can see the mouth of the character that looks like Kenny (but isn't). What is not different is the moral lesson at the end told by one of the boys. This idea was also taken up for the show and appears at the end of almost every episode.
