Yowies, sometimes known as “yahoos” because of the eerie, echoing cry they make, are fearsome ape-like nocturnal predators that stalk remote forests and mountainous regions. Towering between 7-11 feet tall, these hulking creatures are covered in thick, dark or reddish-brown hair. Yowies are carnivorous with a particular taste for human and demi-human flesh.

Their long, powerful arms end in sharp claws and their slavering maws are full of jagged teeth. As part of its nocturnal adaptations, the yowie has Darkvision with a range of 120 feet.

Yowies are found either alone or in small family groups, they are fiercely territorial and aggressive in their lair, fighting to the death to defend it (treat their morale as 11 when encountered in their lair). Despite their animalistic appearance, they possess a cunning intelligence, setting rudimentary traps or using basic tools. They usually lair, in caves or dense thickets, usually strewn with the remains of their unfortunate victims and any treasure those victims might have carried.
