Insert cartoon for Southwest Reprise Theatre's production of "The Very Merry Xmas Carol Holiday Adventure Show", showing the horrors of the dreaded "Xmas", which is the evident villain of the story -- or so it seems, at least.
It's a silly cartoon for a silly holiday play. Do not take too seriously.
A number of clip-art pieces are used here from online clipart collections. As far as I know, they do not require attributions (and I have lost track). I was very sad to find that "Open Clipart" is still shut down, or I'd have relied on that.
The sounds are from FreeSound.org, mostly CC0, although a couple of "Attribution-Only" (CC By) sounds were also used (by users tomlija and Marec -- these are parts of the children-playing ambience and the Xmas's rumbling sound, respectively).
I also could not resist the Wizards call-out, and I think that sample is sufficiently altered and short to fall under "fair use".
I'm not going to assert any additional copyright restrictions on this -- my animation work here is CC 0 / Public Domain. You only have to worry about the noted By-licensed sounds. I'd appreciate being credited if you use it, but it's not a requirement.
