The Palis is a foot-licking jinn of low intelligence that drains the blood of sleepers by licking their feet. It can be easily thwarted by two people sleeping together with their feet under the covers and their heads sticking out from opposite sides of the bed. From Kitāb-i ʻAjāʾib-i makhlūqāt (The Book of Wonders and Creatures), 1921.
