What it is

The Ao Ao is a legendary monster within the mythological traditions of Guarani-speaking communities. It appears as a terrifying predator that targets human beings for consumption. Descriptions vary between a sheep-like beast with large fangs and a carnivorous peccary. The creature is defined by its relentless pursuit of prey and its role as a source of fear in local folklore.

Where it comes from

This entity originates from the oral traditions of Guarani cultures. It is identified as one of the cursed offspring of Tau and Kerana. Some accounts link it to fertility spirits due to claims of profound reproductive powers. Its name reflects the sound it makes while hunting, a repeated howl that signals its approach to potential victims.

How it is done

The Ao Ao tracks victims across any terrain without stopping. It circles trees to dig up roots and force them down if prey attempts to climb. The only known escape involves climbing a palm tree, which repels the beast. It also consumes clothing left behind. In some tales, it receives disobedient children from its brother Jasy Jatere.
