Billy worries about everything, from shoes that might march out the window to giant birds that might carry him away. One night on a visit to Grandma’s, Billy is so anxious that he can’t sleep. But Grandma has just the thing for a boy like Billy — tiny, colorful worry dolls, made to do his worrying for him. That night when Billy puts the dolls under his pillow, he sleeps like a log. But soon it dawns on Billy that something is not quite right — now he has all those worry dolls to worry about! Leave it to Anthony Browne, with his surreal illustrations and a final clever twist, to come up with a solution that puts Billy at ease at last.
