Olitiau
An Olitiau is a gigantic cryptid bat (or flying reptile) hypothesized to exist in Central Africa. The word, Olitiau likely comes from a fusion of the Ipulo words “Ole” and “Ntya”, a name for ceremonial dance masks used to represent demons. The name may be used by the Ipulo to refer to demons in general rather than to the creature itself.
