A Grinch (possibly the Grinch) is a tall, green furred humanoid monster with a foul disposition and a desire to spoil others' fun as often as possible.  It detests noise, especially that of merry-making, and will try to disrupt such celebrations in what ever way it can.  It is a cunning and deceptive creature.  It has the abilities of a 5th level Thief, and can also disguise itself convincingly (80% chance) if it has time to prepare.  A Grinch prefers to live in remote mountain caves, as far from civilization as it can.  It will avoid direct combat, fleeing instead.
