Jólakötturinn / Yule Cat

From the description: A Hex-mas themed monster/god for those cold Icelandic nights! The Jólakötturinn stalks the Dying World devouring anyone caught wearing old and tattered clothes at Jól. So, basically everyone! At 100 hp, it's unkillable (just like the real thing), but you know, you do you. It could be 50 or 35 or whatever you want. Have fun!
