Explore all kinds of things that go in this delightful board book! Featuring a gently rhyming text and a fantastic sliding surprise on each page, it's perfect for small hands and big imaginations. With the use of easy-to-pull page extenders, a picture of a single digger in the city becomes part of a bustling construction team, and a picture of a single pane flying in a clear sky becomes a scene in which lots of planes are soaring and loop-the-looping in a fantastic display!
