Mbielu-Mbielu-Mbielu is
Lingala for "The animal with planks growing out of its back."
Mbielu-Mbielu-Mbielu is noted to live in the same region as Mokele-Mbembe. With less known of Mbielu-Mbielu-Mbielu than Mokele-Mbembe, other than to say that Mbielu^3 has large planks growing from its back, this creature seems even more mythical than Mokele-Mbembe.
