That Bynum comes up with so many lines to rhyme with “Altoona Baboona” deserves some kind of acclaim, even if the rhymes make readers laugh and groan at the same time. Altoona Baboona is an ape that “gets bored on her dune-a,” hops a “hot air balloon-a” and goes south to “Calcun-a.” On her hot air travels Altoona meets up with a loon-a and a racoon-a, who come back to the dune-a for an evening bonfire and roasted marshmallows. Bynum’s watercolors have a breezy ocean air feel to them, as light and buoyant as her simian heroine. (Picture book. 2-6)
