Bacoo (or "baku") is a figure in Caribbean folklore — a small, mischievous, magical being, often described as a dwarf-like spirit that lives in bottles or hollow trees, grants wishes, or causes trouble. It appears in Guyanese, Trinidadian, Surinamese, and wider Caribbean oral tradition.
Likely West African (Yoruba/Igbo) via enslaved populations — parallels to egbere or abiku concepts. Merged with Indigenous and European folklore elements in the plantation Caribbean.
No specimen, no habitat, no scientific description. It's folklore — like Anansi, La Diablesse, Papa Bois, Soucouyant. Cultural truth ≠ empirical existence.
Guyana has jaguars, harpy eagles, giant river otters, arapaima — real wonders. Bacoo lives in stories.
