The "boogeymen" of PFRPG

I amthinking pf doing an adventure featuring boogeyman inspired monsters. So far I know there are boogeymen, babau, Anniston hags, baba yaga. Anything else inspired or named after boogeymen In various sizes cultures?

Most boogeymen mechanics are little side-gimmicks. Just think of a cool boogeymanish mechanic, write up some flavor for the boogeyman, and tack it on to an existing CR-appropriate monster. That monster can even be human, if you want.

Attic Whisperer. If it touches you it steals your voice, and can then use that voice while you've lost yours. Also, its bite causes fatigue->exhaustion->sleep and the sleeper can only be awakened by the various dispels or killing the attic whisperer. It's formed by a lonely or neglected child's death. It's thematic and creepy as hell.

Penanggalen are a type of folk legend given stats. They are also truly disturbing, especially if you describe the head rising out of the body.

Wendigo are absolutely terrifying native american themed boogeymen.

A male Bard with Perform: Boogey?

There is always El Cucuy. From Hispanic traditions.

Chupacabra is fun for lower level boogeymen.

Anniston hags

Yeah, that Jennifer is the worst. She's a very scary monster.

Don't forget bugbears.

One lets the creature molt, dimension door away, and the skin continues to fight with no indication as to what's happening.

The second causes taxidermied things to rise as undead husks fully capable of enveloping people into their hollow bodies.

Nightmare Lords also work
