Saci-Pererê

He is depicted as a small Black or Black-Brazilian boy who is missing one leg, hopping rather than walking, and who wears a red magic cap alongside a lit pipe that is rarely out of his mouth.

The red cap itself is treated as the source of his power, granting invisibility or the ability to appear and disappear at will, and in some tellings whoever manages to steal it can compel the Saci to do their bidding or can use it themselves for luck.

people are traditionally advised to throw an object, such as a rope tied in knots or a rosary, into the whirlwind to trap him and force him to grant a wish or hand over his cap before being released.

The Saci-Pererê is a trickster figure of Brazilian folklore whose roots are usually traced to Indigenous Tupi tradition and to Afro-Brazilian folk belief.

His mischief is characteristically petty rather than malicious: souring milk, tangling horses' manes into stubborn knots, hiding household tools, spooking animals, misdirecting travelers, and setting small kitchen or household disasters in motion, all delivered with a whistle or laugh rather than any real intent to cause lasting harm.
