The Headless Mule (Portuguese: mula sem cabeça, pronounced [ˈmulɐ ˈsẽjm kɐˈbesɐ]) is a mythical character in Brazilian folklore.
According to most reports, the Mule is condemned to gallop over the territory of seven parishes each night (just as the Brazilian version of the werewolf[3]).
Depending on the source the headless mule may have a placeholder head and mane, made of the fire it spews, to which a red-hot iron bridle is tied.
In any case, when the mule changes back to human form the accursed woman will be completely naked, sweated, and smelling of sulfur.
Instead, one should either be brave enough to remove the bridle or spill its blood, or else just lay face down on the ground, covering teeth and nails (as well as anything that shines), and the mule will hopefully fail to notice the stranger's presence and trot away (because it has poor vision).
