Tulliver is a little rabbit who hates washing his face. One day he decides he has had enough, and leaves home to live in a burrow under a big oak tree at the far end of the field.
I've read Tulliver's Tunnel to the 4- and 5-year-olds in the preschool where I teach. They love this story of a young rabbit leaving home because he doesn't want to wash his face.
