What's That Noise? invites young children to investigate who exactly is calling them from inside the book. Children will delight in following the clues by "tip-toeing" with their fingers through an empty forest, braving a terrible storm, holding their ear up to the book to discern where to turn next, and creating a shelter when danger looms. A story that can only be told using fingers, eyes, ears, and noses, What's That Noise? engages readers on all levels, and shows that building a friendship takes time, patience, and an adventurous spirit.
