The chwal takes on the behaviour and expressions of the possessing lwa; their performance can be very theatrical. Those believing themselves possessed by the serpent Danbala, for instance, often slither on the floor, dart out their tongue, and climb the posts of the peristil. Those possessed by Zaka, lwa of agriculture, will dress as a peasant in a straw hat with a clay pipe and will often speak in a rustic accent. The chwal will often then join in with the dances, dancing with anyone whom they wish to, or sometimes eating and drinking. Sometimes the lwa, through the chwal, will engage in financial transactions with members of the congregation, for instance by selling them food that has been given as an offering or lending them money.
