1.
A very rare marsupial found exclusively in the area surrounding Greenville, North Carolina. Teesh are known to eat non-food items such as rocks, dirt, clothing, condoms, rubber bands, or string. Teesh are also known for their smell. The smell is extremely pungent, and resembles a combination of rotten eggs, doo-doo butter, old cabbage, goat cheese, gym socks, mildew, and deer piss. The Teesh has no true niche in its environment, it is simply a scavenger and a drifter, usually resting on a foregin couch before arising at night to feed. The National Wildlife Federation has put the Teesh on its list of proctected species and asks any individual who comes across a Teesh to return it to the National Teesh Wrangler, Mr. Daniel Thomas Bricker of Greenville.
