Convertible Tractor is a fun storybook that can also be used as a playmat and a sit-in vehicle for toddlers. Once unfolded, parent and child can read the text, which describes an exciting journey to a farm. The bright, busy illustrations are packed with colourful details including different animals and people to meet. Laid on the floor, the book can also be used as a playmat. The boards can then be refolded into a large, sturdy tractor that a child can sit in and pretend to drive.
