Sly Monkey snags the zookeeper's keys, bolting from his cage for a whirlwind mimicry spree through city streets and homes. From barber chairs to baby baths, he apes antics with gleeful chaos until sunset fatigue sends him scampering back to mum. Amstutz's zany collages swing with Ahlberg's zippy rhymes, a cheeky escapade celebrating copycat curiosity and cozy returns.
