Eloko is a term in a Mongo-Nkundo language referring to a kind of dwarf-like creature that lives in the forests. They are believed to be the spirits of ancestors of the people living there. Legend has it that they haunt the forest because they have some grudge to settle with the living and are generally quite vicious. Biloko live in the densest and darkest part of the rain forest in central Zaïre, jealously and ferociously guarding their treasures: the game and the rare fruits of the forest. Only intrepid hunters are said to enter the deepest forest and survive, because in order to be successful, hunters have to possess strong magic, without which they would never see any game at all. There are many tales about wives who insist upon joining their husbands in the forest only to faint as soon as they see their first Eloko.
The Biloko live in hollow trees and are dressed only in leaves. They have no hair; only grass grows on their bodies; they have piercing eyes, snouts with mouths that can be opened wide enough to admit a human body, alive or dead, and long, sharp claws. They possess little bells, which, in Central Africa are believed to be able to cast a spell on passers-by. Possessing an amulet or a fetish can offer protection from this type of magic.
