The sun has gone down, the stars are out, and it is officially time to hit the hay. However, Little Critter is absolutely not ready to close his eyes and go to sleep just yet. Using his powerful imagination, he tries every trick in the book to delay his bedtime routine. One minute he is a tough cowboy rounding up wild horses, the next he is a fearless space cadet exploring the galaxy, and then he is a loud sea monster causing a splash in the bathtub. Despite all his brilliant disguises and energetic games, his patient parents are determined to guide him toward his bedroom. Eventually, even the bravest heroes and fastest race car drivers start to feel their eyes getting heavy. Snuggle up with a hilarious and familiar struggle as one very creative child finally admits he is tired.
