The Toyol (Southeast Asia)
A familiar spirit from Malaysian and Indonesian folklore, often used in black magic. A Toyol is the reanimated fetus or stillborn child of a human, controlled by a master to steal or cause mischief. It appears as a naked, green-skinned child with red eyes. It can be warded off by scattering coins or toys, as it is easily distracted.
The Namahage (Japan)
Demonic-looking figures (men in ogre masks and straw capes) who visit homes during the New Year in Akita Prefecture. They ask questions, saying if children have been lazy or disobedient. The ritual is meant to scare children into good behavior, after which the Namahage are offered sake and revealed to be community members, blending myth with a community reinforcement of norms.
“a naked, green-skinned child with red eyes” that’s creepy!
Reminds me a little of the mystery of ‘the green children of Woolpit, Suffolk’. That’s worth looking up.
