The series focuses on a family of anthropomorphic lions operating and living in a large, busy library starring alongside a cast of unusual characters such as Click, an electronic, anthropomorphic computer mouse. The program's format is intended to promote literacy and reading, and is perhaps most notable for sections of every episode in which the lions introduce an existing picture book to the audience and read it, a book that often presents a moral. Some episodes even have featured adaptions of well-known folk-tales or ancient myths or fables, while others have featured popular storybooks such as 'Click, Clack, Moo! Cows that Type', or shown the lions learning or benefiting from the lessons presented by the story. Aside from this, the series often features an array of educational segments formatted each in its own distinctive style, particularly parodies of well-known media redesigned educationally for younger audiences or simple animations, some sketches more repetitive than others. A distinctive feature of the series is that it is virtually never set outside of the library, as it usually chronicles the lions' experiences within it. Another segment features a pair of pigeons named Walter and Clay comically infuriating a living bust of the library's deceased founder, Barnaby B. Busterfield III, located in an upper section of the library, that is normally intended for comic relief.
