Bholes are huge, slimy worm-like creatures, at least several hundred feet long. Because they avoid daylight and are covered in viscous goo, their features are nearly impossible to discern. Similar creatures called bholes exist in the Vale of Pnath in the Dreamlands.
Now Carter knew from a certain source that he was in the vale of Pnath, where crawl and burrow the enormous bholes; but he did not know what to expect, because no one has ever seen a bhole, or even guessed what such a thing may be like. Bholes are known only by dim rumour from the rustling they make amongst mountains of bones and the slimy touch they have when they wriggle past one. They cannot be seen because they creep only in the dark. - H. P. Lovecraft, The Dream-Quest of Unknown Kadath (fiction).
