Ebu Gogo (Flores)
The Ebu Gogo are a group of human-like creatures that appear in the folklore of Flores, Indonesia. In the Nage language of central Flores, ebu means "grandparent" and gogo means "one who eats anything". A colloquial English equivalent might be something like "old glutton". The Nage people of Flores describe the Ebu Gogo as having been able walkers and fast runners around 5 feet tall.
They reportedly had wide and flat noses, broad faces with large mouths and hairy bodies. They were said to have murmured in what was assumed to be their own language and could reportedly repeat what was said to them in a parrot-like fashion. The legends relating to the Ebu Gogo were traditionally attributed to monkeys, according to the journal Nature.
