Standing guard over the forest, stern Old Owl serenades a progression of animals—among them, a hungry raccoon, a hopping frog and a smelly skunk—with the song, “Whooo’s there?” Rendered in rich nocturnal hues with thick flowing lines and geometric forms, the animated, double-page spreads complement quatrains that are replete with alliteration and animal sound effects. Variety in both the pleasing rhymes and artwork—including intermittent visits from the moon and a cat-rat chase—will keep the pages turning. While the small format may disqualify it from group storytimes, this tranquil and engaging bedtime sojourn is just right for one-on-one sharing. (Picture book. 3-5)
