For busy grown-ups and the children who love them, here is a charming picture book about the best way to spend a sunny day, kid-style versus adult-style.

Big Mouse works in the garden-digging, planting seeds, and picking weeds. It's hard work, and he'd love some help from Little Mouse. But his young friend seems too preoccupied with daydreams and games to lend a paw. Just when an exhausted Big Mouse has had enough of Little Mouse's laziness, Little Mouse proves that his day has been busy, too.

Big Mouse and Little Mouse, stars of the bedtime book The Very Noisy Night, will amuse parents and children with another all-too-familiar battle of wills. Their lively story is paired with colorful, cluttered scenes in which clothespins, sink plugs, forks, and other cheerful household detritus find second use as mouse tools and furniture-a homey setting for a true-to-life tale.
