Spawn of Shub-Niggurath (AC 14, MV 120, HD 6, Multiple Alignments \[intelligent\]): An Orange humanoid with a smooth hide and 3 heads. One head is humanoid (and Lawful), one head is robotic (and Neutral) and the last head is bestial (and Chaotic). When first encountered, or whenever the creature is under stress, roll a d6 to see which head is currently in control of the beast: 1-2 - the humanoid; 3-4 - the robot; 5-6 the monster.
Most hex descriptions in Carcosa are kind of crazy.
