Contaminated

This story is based off a dream I had with a surprisingly good storyline. This is a sci-fi zombie adventure story I suppose, so be warned of zombie descriptions and elements of gore.

Need-to-know information:
This planet is not earth. It is an alien planet humans have discovered years ago and have colonised due to Earth having a lack of oxygen. It's called Cacatakkara, home to the species known by: Taskanarians Taska's for short. The planet is 92% water, but only around 5000 humans and 200 Taska's live there.

Taska's are basically cats, but way more human than cat. They have tails and a face of a cat but abnormally coloured, like white and purple.

Humans have lived there for over a century now. It is set in the time 2133.

Introduction:

There has been a strange liquid leaking from the mountains of Sundai, but no one has really thought to worry about it, not even the home species. They called it the Sundias water. Soon, it began to infect normal water, which freaked a small village as the water was turning thick, green and yellow.

The village didn't evacuate in time. 58 Taska's and humans have formed into destructive melting monsters. They have destroyed everything in their village, and they have now begun to mangle the nearby desert town, spreading the infection to other innocents...
