Our hero (a cheerful little guy in a yellow jumpsuit) receives the narrator's good wishes and heads out of town. He travels through a wide variety of colorful Seussian landscapes and cityscapes and finds himself in many different situations--some exhilarating, some depressing, some downright frightening.
At one point he gets stuck in the Waiting Place, where "everyone is just waiting ... waiting, perhaps, for their Uncle Jake / or a pot to boil, or a Better Break / or a string of pearls, or a pair of pants / or a wig with curls, or Another Chance."
At one moment our hero is riding high on an elephant's back with a triumphant banner flapping overhead. At another he's rowing a tiny rowboat through a black lagoon full of howling, long-necked Hakken-Kraks. The plucky protagonist faces up to each challenge and extricates himself from each Hang-up, Lurch, and Slump. His success is "98 and 3/4 percent guaranteed"!
