Floofs resembled short humanoids, commonly with bald heads. Over time, they evolved to become experts in hiding. This allowed them to find the one spot that no-one was looking at in a room full of people, which would keep them out of sight from people. They generally stalked humans or other humanoids, causing mischief in the person's life. However, sometimes the Floof became possessive and began to cause more serious problems. They probably had superhuman speed, as they could travel to places where no-one could see them extremely quickly. (PROSE: Corner of the Eye)
