Baabwaa and Wooliam
Baabwaa is a sheep who loves to knit. Wooliam is a sheep who loves to read. It sounds a bit boring, but they like it. Then, quite unexpectedly, a third sheep shows up. A funny-looking sheep who wears a tattered wool coat and has long, dreadfully decaying teeth. Wooliam, being well read, thinks he recognizes their new acquaintance ... could it be the Wolf in Sheep's Clothing?
