malafu

He can discover who "ate the heart" of the chief who died yesterday; who caused the canoe to upset and gave lives to the crocodiles and the dark waters of the Congo; or even "who blighted the palm trees of the village and dried up their sap, causing the supply of malafu to cease; or who drove away the rain from a district, and withheld its field of nguba" (ground-nuts).
