Have a bath, work out, take the car for a spin . . . the busy, lovable mouse in this picture book has one long "To Do" list! But he can't even get started until the family he shares his house with goes to sleep. So he spends the day resting in his mouse hole waiting patiently for the night to come. When it finally does, and the family is tucked in bed, this little mouse goes on one busy adventure!

A simple, rhyming text describes the family's busy day and peaceful night, while Fumi Kosaka's clever, playful illustrations let us know what the mouse is up to.
