KHOLOMODUMO
Folklore of Southeastern Africa
This is the name of a gigantic monster in the legends and folk beliefs of the SOTHO people of southeastern Africa. KHOLOMODUMO existed from the time of creation and was so voracious that it ate every living human except one. This woman survived by hiding and eventually gave birth to twin boys. They and a dog decided to track and destroy KHOLOMODUMO. When they succeeded, the whole of the devoured humanity was restored and came out from inside.
