Wikipedia:WikiSheep

WikiSheep (Ovis wikipediensis) is an animal that roams the fields of Wikipedia. Its very cuddly and gentle, but can eat articles that are prohibited.

Differences from WikiGoat
Unlike its stubborn cousin, WikiSheep can eat prohibited articles without noticing it. It can come from "being sheepish", or not knowing that it's against Wikipedias rules to eat a good article.

What to do
If you see a Wikisheep eating a good, or close-to-being good article, try to be a shepherd and redirect it to eat more vulnerable articles: it will listen. Don't provoke it, otherwise a WikiSheep might turn into a WikiRam. If that happens, contact a butcher, which will slaughter it.
