I don’t know how it happened, but Cthulhu has somehow insinuated itself into the Christmas holidays.

Flickr user LiquidNight used an artificial tree, some blue lights, and 50 Cthulhu Tentacles to create this “A Very Lovecraft Christmas” with this Cthulhu Christmas Tree.

Red Wasp Design has been hard at work making all of your Cthulhuian dreams come true this holiday season. It began with the Cthulhu Christmas Calender app and now comes new information and goodies from Red Wasp’s Call of Cthulhu: The Wasted Land game.

The game is based on the many works of author H.P. Lovecraft, and now has both a release date and shiny new hi-def screenshots to take a peek at, which you can see below now.

Nothing says Christmas like Cthulhu!

The folks over at Red Wasp have designed a great app for the holiday season — the Cthulhu Christmas Calendar. Starting December 1, you can have adorably illustrated renderings of H.P. Lovecraft’s terrifying creations help you countdown the 25 days til Christmas on your smartphone or iPad.

This unique digital advent calendar contains an original illustration for each day that combines classic Christmas imagery like mistletoe with figures from H.P. Lovecraft’s Cthulhu Mythos, like Shoggoth mailing a letter to Santa, who, as we know, will find out if he’s been naughty or nice.

Writer H.P. Lovecraft died in 1937 at 46 years old, with poverty and malnutrition being contributing factors to his early death. It’s with that in mind that Ross Lockhart, the editor of The Book of Cthulhu, came up with a 24-hour Twitter challenge to help feed the hungry. This Thanksgiving, if you donate to a food bank or any charities that help feed the hungry, you can enter to win The Book of Cthulhu, an anthology collecting 17 tales of cosmic horror inspired by the writer Lovecraft.

To enter to win, make your donation, then sign on to Twitter and tweet the following message:

I fed Cthulhu [your donation] to [organization] #FeedCthulhu @lossrockhart
