One Chloroform sleep paralysis demon!

These sweet little split-colour critters want nothing more than to enter your room, and make themselves at home amongst your other plushies.

They're docile, cuddly, and weighted to help their host sleep. Their tail is sometimes scented with a sweet pheromone that also aids in aromatherapy.
Make sure to save any spare bones you find, skeletal sappers need bones to survive...and well, you don't want to lose yours.
