Henry and Mudge and the Starry Night — Cynthia Rylant

In this seventeenth book of their adventures, Henry and Mudge go camping with Henry's parents. They'll go on hikes and smell good smells. They'll see deer and raccoons and waterfalls and rainbows. Henry's mother will cook camp food and Henry's father will sing sappy old songs, and they'll all lie on their backs and look at the stars (except for Mudge -- he'll chew on a log, instead). And at the end of a perfect day, Henry and Mudge will snuggle in their tent and dream wonderful green dreams.
