Around the World in Scary Creatures

A carved tupilaq (an avenging golem-like creature
created by a Greenlandic Inuit shaman)If you think of horror and supernatural creatures, the list you write will probably be pretty short, with vampires, ghosts, witches, demons, zombies and were-creatures as the main players, and maybe the odd Celtic or Japanese creature thrown in, or perhaps an alien.
I assume the Erqigdlet, ijiraq and haietlik failed to make that list. If you're curious, these are mythological creatures from Greenland, Baffin Island, and British Columbia respectively. The first are a race of creatures with the head, arms and torso of humans, and the lower bodies of wolves (my Tunumiit ancestors suggested these creatures might come for you if you were too picky about choosing a spouse!); the second are shapeshifters who lure children out into the snow to freeze; the third is the 'lightening snake', a sea-serpent that hunts giant prey along the coast (and occasionally slurps up an unwary human from the beach). 
That's just a taste of the wealth of under-appreciated supernatural creatures that can be found in folklore around the world. There's no need for more recycled (and sparkly) vampires when you can have a sasabonsam, a blood-drinking, iron-fanged creature from Akan (Ghanan/Tongan) mythology that lurks in trees to leap out at its victims. 
Now just to be clear, I'm not advocating willy-nilly cultural appropriation! Instead, I'm suggesting that you expand the range of settings and characters beyond Generic Anglo-Americans in or Lovecraft Country. Why not have an urban Maori family as your protagonists, or have the mysterious disappearances strike in rural central Mexico? There are so many opportunities to create fresh, interesting stories that reflect the many pieces of our global mythology and imagination that it would be a shame not to use them.
