Convertible Train is a fun storybook that can also be used as a playmat and sit-in vehicle for toddlers. Once unfolded, parent and child can read the text, which describes the journey of a busy train. The bright, lively illustrations are packed with colourful detail to keep a child interested. Laid on the floor, the book can also be used as a playmat. The boards can then be refolded into a large, sturdy steam train that a child can sit in and pretend to drive.
