South African readers will be familiar with the tokoloshe. The rest of you would do well to be aware of him. He is an evil little sod, most active at night. The only way you can be sure of sleeping safely is to put a brick under each leg of your bed so he can't reach you.
Here are a couple of songs about him. The first is by the late, great King of Tsonga Disco, Peta Teanet. The second is by the still living King of Thing, John Kongos.

"Tokoloshe Man" - John Kongos
