It comes as a delight how much fun can be wrung from the words "moo" and "hoo."
Cow and Owl are young chums (and bear a keen resemblance to Frog and Rabbit, the spawn of Ryan and Lowery's terrific first collaboration, Ribbit Rabbit, 2011). Being what they are, the words moo and hoo spin freely in their orbit and trigger like words depending on what they are doing. They fix things together: "Moo Hoo. Glue Shoe." They trick-or-treat together: "Moo Hoo. Boo! Boo!" Although Ryan fills in some narrative context, it is these tiny, rhymed sound-words that express the emotional range of the story, which is whopping in its brevity (aided and abetted by Lowery's dear, spindly creatures, with their disarming gestures and primitive toys). When a young kangaroo enters the scene—"Who you?" "Roo new"—Cow and Owl are standoffish. Roo wants to join in—"Roo too?"—but no deal. "Roo blue." It breaks your heart. Cow and Owl do see the error in their ways, and Kangaroo enters the fold. "Woo hoo!"
A winning display of finding the high ground and paved with particularly sweet verbal compression. (Picture book. 3-6)
