When a herd of poky sheep slow the Goodnight Train to a crawl, the engineer's quick thinking (and counting) has them rolling along in no-time--until one tricky sheep sends the train and its sleepy passengers tossing and turning! The clickety-clack cadence of the poetic text is sure to lull listeners to sleep, but not before they take in the candy-colored, dreamy bedtime landscapes full of delightful details to discover. All aboard!
