This 30-minute direct-to-video collection featured Mother Goose stories starring William Wegman's dogs. In the video, Mother Goose tries to teach her son Simon how to rhyme using some of her famous rhymes. The tape was released on September 2, 1997.

Many of the nursery rhyme segments have aired on Sesame Street as inserts with minor differences in music, editing, and sound effects.
