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.

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.
