Slithering forward is a snake-like creature seemingly composed of matted, greasy hair. Its face is vaguely canine and bears wide, staring eyes.

Despite their comical, almost cute appearance, the urban monsters known as keukegen are malicious creatures that delight in spreading disease and suffering. The origins of keukegens are debated—some scholars believe they arise spontaneously from collections of dust, hair and lint, whereas others believe that they reproduce like normal creatures, releasing airborne spores which settle in these messes and grow to maturity. What is known is that they gravitate to dirty and unhealthy areas and spread this squalor into outright pestilence. Minor ailments such as colds, fevers and indigestion are everyday occurrences where keukegen live, and a single keukegen can easily turn an entire city block into a sick ward.
Due to their urban habitats and love of filth, keukegen and binbōgami occasionally come into contact. The capricious kami, surprisingly, view keukegen as a menace to be eliminated, leading to pitched battles between the two shabby creatures. A binbōgami is more than a match for a single keukegen, so keukegen in an area patrolled by a binbōgami aggregate into clots for mutual defense.
A keukegen grows up to four feet long and weighs about eighty pounds. Despite their seemingly formless bodies and snake-like movements, they possess over two dozen centipede-like legs, which they use to scuttle up walls and ceilings.
