The Gannan Yak is a breed of Yak living in the high altitudes of the Tibetan Plateau. As opposed to other cattle, selective breeding isn't as advanced in the Domestic Yak.

Yak is managing to lactate milk from her udders, and she finds a camera.

”Oooo, a camera! How about I give you a face full of milk! How’d you like that?!”

Just like that, Yak squirts her udders’ milk onto your lens face, covering your point of view with milk as it drips down your lens face.
