Saci

Saci Pererê is a very playful character in Brazilian mythology. The color of his skin is black and he has only one leg. He is always depicted smoking a large pipe. He wears a red pointed hat, which gives him magical powers like the ability to appear or disappear whenever he wants to. He loves to play pranks like distracting people who are cooking so that the food burns on the stove. Some of his other pranks are to hide kitchen utensils, bang doors or letting animals penned in corrals loose. Another favorite of his is to startle travelers or hunters who venture alone in the forests, by whistling loudly in their ears. After this, he appears to them in a cloud of smoke, asking them to light his pipe. During full moon nights, he hops onto a horse and gallops merrily around the countryside.He likes to braid the horse's mane, too.
