"Mix it up and pour it out with Big Boy the cement truck! Discover how concrete is made and all of the different things it can be used for. The two cement trucks, Big Boy and Tiny, along with their good friend Sally the front end loader, work hard all day making and delivering cement, constructing roads and pouring sidewalks. Follow Tiny to the construction site and watch an enormous crane lift massive loads of cement effortlessly to the top of a 40 floor sky scraper. These delightful characters deliver BIG sounds, BIG pictures and BIG thrills."--Container.
