Parasite Grass

Parasitic grass which lives of humans. It plants its seed into a target's nerves to control the now appointed host's appetite. Such humans will first feel unusual hunger pangs, and then will try to feed on any living thing nearby. The parasitic grass then absorbs the nutrients from the host to grow, an in its final stage, the grass burst out of the host, and lays its roots onto the ground, dead host and all. These plants are very deadly, but they can be culled by removing them from the body early in its sprouting stage, so the host simply has to stay calm and follow basic procedures to counter their parasitism.
