A spirit of small stature that pelts stones at houses and moves objects within a house. He is supposed to live on banana and milk. Stories abound of the existence of bacoos in Georgetown and other areas in Guyana. Could have come from Surinam and are said to be trapped in a corked bottle unless released. Active mainly at night, it is said that a satisfied bakkoo will answer the wishes of its owner.

'Baku' in many West African languages means 'little brother' or 'short man'. It also is related to the word the word 'bacucu' meaning 'banana'. In West Africa, the short races (such as the pygmies) were believed to have magical powers. This seemed to have been brought to Guyana, where the short races, or 'bakus', were still regarded as having magical powers.
