A young boy wonders aloud to a rabbit friend what he will be when he grows up and imagines some outrageous choices. “Puddle stomper,” “bubble gum popper,” “mixing-bowl licker,” “baby-sis soother” are just some of the 24 inspiringly creative vocations Spinelli’s young dreamer envisions in this pithy rhymed account. Aided by Liao’s cleverly integrated full-bleed mixed-media illustrations, which radiate every hue of the rainbow, and dynamic typesetting with words that swoop and dive, the author’s perspective on this adult-inspired question yields some refreshingly child-oriented answers. Given such an irresistible array of options—“So many jobs! / They’re all such fun”—the boy in the end decides, in an exuberant double gatefold, “I’m going to choose… / EVERY ONE!”—a conclusion befitting a generation expected to have more than six careers each. Without parents or peers around to corral this carefree child’s dreams, the possibilities of being whatever one wants appear both limitless and attainable. An inspired take on a timeless question.
