'Slim-Pickles and Jolly spend all day in their shed inventing knick-knacks and nobblers and thing-a-me-jigs; rabbity-flunkets and skippety wigs. But when the air grows thick with pollution they decide what the world really needs is a super-parp-buster! An entertaining and rewarding picture book for 5-8 year-olds that takes a light-hearted look at the importance of environmentally friendly transport and other issues.'
