 Why does the Sand God keep the webfoots around?
The sand-thing was powerful, lonely and strange. A gray, funnel-shaped cloud of dust stood off to his left. Weather control made cyclones and other climatic phenomena on earth practically non-existent. He was here and Earth was somewhere up there. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? He became so absorbed in doing this that he failed to notice how the wind devil drew closer and closer, but when he inhaled the first grains of sand, the realization of what was happening dawned with a flash of fear. There, at the cavern entrance, the wind devil writhed and undulated in a brilliant harmony of colors.
 It amuses the Sand God to watch the webfoots evolution.
