This zombie-like creature is just a pile of claws, teeth and rotting flesh with legs.

It seems to have been infected with some parasite that makes it more aggressive than usual.

This is something that has earlier been seen in mice and ants back on Earth, but not on Calypso.

You should eliminate it before it can spread the parasite!
