Top of the World by Holly Hobbie

When Toot doesn't return home to Woodcock Pocket as expected, Puddle becomes worried and decides he must go find him. His search leads him on a remarkable adventure, and to new summits of friendship. As ever, Holly Hobbie's extraordinary watercolor illustrations are at once funny and moving as they bring to life this whimsical tale of the inimitable Toot and Puddle.
