Looney Labs 2013 Christmas Present contains four card add-ons for four different Looney Labs games. After the initial Christmas 2013 gift release, the pack is now available for purchase in some retail locations. Contains the Cards: Live Woolly Mammoth (Chrononauts) - a new artifact for the game, something neat to collect. Knock, Knock (Monster Fluxx) - a new goal for Monster Fluxx, you need the Spooky Door and Angry Mob of Villagers to win! Fluxx or Looney Pyramids (Choose One) - It begs the question of which one would you choose: Fluxx or Looney Pyramids? Scramble Colors (Fluxx: The Board Game) - A new Action card: "Gather up all color cards currently in use, shuffle them together, and deal them back out." It really switches things.
