Meet Ernest, an endearing moose, but one so big that he can't fit inside the book. 'He struggles to shimmy, shuffle and shunt in forwards', but still there's part of him hanging off the page. His little chipmunk friend lends a hand and then has a bright idea about how to solve the problem. Important mathematical lessons about size, shape, volume and scale are delivered with rich language and great humour.
