A baby spirit. The first story related to Kuman Thong was found in the Thai book “Khun Chang Khun Paen”. The way to get this spirit is quite horrible: one must get a dead fetus and burn it in order to obtain a small body. Then dark incantations are cast to insert black magic inside. The Kuman Thong spirit is supposed to warn and protect his owner in case of danger. The owner must also feed and protect it.
