Stock up on all the Munchkin Kill-O-Meters, T-Shirts, Cthulhu Dice Bags, and Munchkin Blank Cards you could ever want. Need more gift ideas? How about a Pink Cthulhu Shot Glass? You can pick up all the different colors of Munchkin Jumbo d6 sets. Perhaps now would be a prime time to grab your very own copy of Revolution! and Revolution! The Palace. Heck, grab Chez Geek and Frag Gold Edition while you're at it.
While you are at it, get a Christmas Chibithulhu too!
