Beyond the bustling modern Australian cities is the outback.

It's a land that's ancient, remote, and deadly.

Animals here evolved in isolation.

Marsupials with pouches, mammals that lay eggs,

flightless birds that can kill with one kick.

And these are just the animals we know about.

People disappear here.

Camp sites torn apart.

Blood smeared across tree trunks.

Claw marks and footprints that don't belong to any known animal.

But the locals know what they are.

They have stories.

Warnings.

The land doesn't just hide these creatures.

It protects them.

And sometimes the land gets hungry, and those creatures have to hunt.

In the forests of Eastern Australia, you hear the typical sounds of any forest, wind rustling through the trees, birds, the chatter of small animals. But there's a sound that stands out, almost human, a deep growl that rattles with every breath.

Aboriginal people have several names for it.

Dulaga, Quinking, Yahoo! Yahoo! Why?

Sorry, sorry. All those names sound like websites from the 90s. Please, go on.

Well, the settlers gave it a name that stuck, the Yowie.

Yowie?
