The Ngondo is yearly festival in Douala, Cameroon. A ceremony is performed by the jengu cult, in which a devotee enters the water to visit the kingdom of the miengu. Miengu (plural for jengu) are mermaid-like spirits with long hair and beautiful gap-teeth, who bestow good luck to devotees, cure diseases and allow them to communicate with the world of spirits.
