An Auckland resident was left puzzled when she heard a "mythical" creature making 'alien-like' noises outside her Mt Albert property on Monday evening.
The resident, who wished not to be named, posted the mysterious video to a local Facebook page asking: "Does anyone know what kind of animal/mythical monster is making this sound?"

The video shows the resident shining a torch into the darkness of their backyard while a spine-chilling noise can be heard ringing out of the bush.
Some commenters responded in horror, while others identified the "monster" as a possum.
A spokesperson from the Department of Conservation confirmed the alien-like noise as a possum.
"Definitely a possum, they normally make this sound when they've met another one," they told Newshub.

Researchers have documented possums making 18 different sounds, according Australian Geographic.
The sounds include "grunting, growling, hissing, screeching, clicking and teeth-chattering calls, many of which would not be out of place on a horror movie soundtrack".
