Ao Ao

"Ao Ao is the sixth son of Tau and Kerana, he is one of the 7 Legendary Monsters of Guarani Mythology, and maybe he is the most dangerous of all 7 brothers, he is also known as “The Lord of the Mountains”.
Ao Ao is a big and ferocious monster, similar in appearance to a sheep, with a long fang, like a boar. He is a voracious predator, they say that he only feeds on humans, a practice considered cannibal, since he is the son of a human, his mother Kerana.
He is capable of everything to capture his victim, he is a tireless creature. If pursued by Ao Ao, the only way out is to climb a palm tree, which is considered a sacred tree. If you climb on any other tree, Ao Ao will circle the tree, howling incessantly and eventually knocking it over. Ao Ao would also feed on the disobedient children delivered by his brother, Jasy Jatere."
