Book and toy combination

A book system comprising:

• a. a first outer cover having a substantially planar body defining a first aperture extending therethrough;
• a second outer cover having a substantially planar body defining a second aperture extending therethrough;
• and
• at least one inner element located between the first and second outer covers, the or each inner element having a substantially planar body defining an inner element aperture extending therethrough;
• wherein at least a portion of the first and second apertures and the or each inner element aperture are aligned with one another to define a receiving aperture extending through the book;
• wherein the planar body of the first outer cover defines a first edge portion, the planar body of the second outer cover defines a second edge portion, and the planar body of the or each inner element defines a third edge portion, wherein the first, second and third edge portions are aligned and engaged with one another to form a spine;
• and
• b. a toy that is reversibly engaged with the receiving aperture, wherein the toy comprises arms that occupy substantially all of the receiving aperture and extend through the receiving aperture to form a closed loop around a portion of the spine to attach the toy to the spine of the book system, and wherein said closed loop can be reversibly opened to release the toy from the book system.
