Operating on the principle that it’s never too soon to form career plans, this primer introduces a porcine post-toddler for whom bath time offers a chance to dream about water-related occupations, from deep-sea diver and submarine captain to long-distance swimmer, or maybe champion surfer. Printed on large, heavy cardstock, half of each spread unfolds into a different shape, sometimes in stages that artfully add to the drama—“Or perhaps I could be a lifeboat pilot . . . [unfold] speeding through crocodile-infested waters . . . [unfold] to rescue all my friends.” The last, cleverly folded in fourths, begins in a sailboat and opens to a view of the world around which PiggyWiggy and his friends would travel. The oversized text, simple, crayon-drawn forms, and saturated colors give this plenty of visual appeal, and even children able to navigate the relatively challenging vocabulary will enjoy diving into PiggyWiggy’s mini-adventures.
