Criaturas Lendárias: Mythical Creatures of Brazilian Folklore (2016)

From publisher blurb:

A book of monsters and supernatural beings, drawn from the legends and folktales of Brazil.

Stats are provided for Malandros.

There are 12 entities described within these pages. Each entry comes with an illustration and 2 or 3 story seeds.
Because this is written for use with Malandros, which takes place in Rio de Janeiro, most of the seeds involve bringing the monsters into a city setting. Their natural habitat tends to be more rural: they're largely creatures of the forest, river and field.

The creatures are:

• Boitatá - a giant, headless snake with the horns of a bull and enormous fiery eyes.
• Boiúna - an even gianter snake, a vengeful river spirit that sinks boats and controls lightning, among other things.
• Curupira - the guardian of the forests, a goblin-like figure with backwards feet.
• The Devil - you know, Satan.
• Dry-Body - an evil strangling spirit that dwells inside tree trunks.
• Encantado - an underwater spirit that kidnaps and/or falls in love with humans.
• Boto - a kind of encantado that turns into a river dolphin and enjoys parties.
• The Grazing Boy - the ghost of a slave boy who died horribly.
• Headless Mule - a cursed woman who turns into a headless mule and gallops through the night.
• Lobisomem - basically a werewolf, but there are different legends about them in Brazil.
• Saci - a mischievous one-legged elf.
• The Satanic Head - a terrifying predatory floating head.
