Created by [[Gorbert Vanhousserhoffen]] in the first season, Symbiotic Grass looks exactly like regular grass, except that it has the tendency to wriggle and squirm when people are near it.

When a person lies in the grass, it rubs gently against them and produces the most soothing feeling of peace and tranquility. A person lying in the grass feels well rested, carefree and happy. In return, the grass feeds on the contentment in creates in its host, thus forming a symbiotic cycle.

There are no adverse effects to lying in the grass, but be warned: pulling yourself away from such contentment is very difficult. If you can't summon up the willpower to roll off of the grass, you may find yourself spending quite a bit of time there. Not that you'll mind too much.
