On a winter's day, Jack and Jill scope out the ideal tree branch on which to build. By the next page, spring has arrived, and the kids have started construction. Their progress is mirrored by two robins who are piecing together their own abode. Step by step, the children add the floor, the roof (a brightly patterned quilt placed over rope), the light (a flashlight), the table, the treats, and the friends. At story's end, the robins, who have completed their nest, and other birds sing the youngsters to sleep as they camp out in the cozy construction. The story ends on a triumphant note: "Hooray for the treehouse that Jack and Jill built!"
