Empathetic Lulu laments caged critters' captivity, sneaking past bars to spring lions, monkeys, and more for a midnight menagerie march to her home. Tubby tub squeezes and scooter safaris ensue until zookeepers reclaim the roamers, but Lulu's wild whims spark a dream of "Lululand" liberty. Ellis's exuberant inks erupt with anarchic affection, a rhyming romp rallying animal autonomy for compassionate cubs.
