Plucky lad Luke snags a zookeeper gig at a zoo of belching gurgles, tickly furbles, and squirgal scares. From humple humps to morph mishaps, he wrangles the wild rumpus with rhymes and roars till teatime truce. Ogilvie's doodly doodads and Sparkes's rollicking rhythm roar a riotous rally for budding beast-tamers.
