Crypt Monster Universe
Crypt TV Wiki; YouTube

Crypt TV existed as both a YouTube and Facebook channel before I ever started watching it, but I'm fairly sure it wasn't until sometime after I started watching it that they decided they'd create a shared universe for various short films and series on the channels. So, a bunch of things that used to be stand-alone stories became retroactively part of that universe, while some newer things would be part of that universe as soon as they were made. Now... I've watched a video (at the top of this page) that explains the history of the CMU, but more things have been added to the universe since that video was made. And on this page, I'm including everything that Crypt TV's YouTube channel includes on its playlist called "The Complete Crypt Monster Universe". However, there are lots of things on that playlist that I never would have considered part of the CMU if they weren't on the playlist. And I suspect some of them are of no importance to the universe as a whole, and might only be included because they were made by Crypt TV (rather than just presented by the channel), though I'm not sure about that. So... whatever.
