"The zookeeper is sleeping while the animals she's keeping, out of habitats are creeping, flying, climbing, stalking, leaping…"

After the zookeeper goes to bed for the night, her animals decide it's the perfect time for a party! Lions and alligators, penguins and giraffes, creatures from all habitats sneak out for some late-night mischief. But when the party starts to get a little too wild, will the animals be caught in their tracks? Bouncy, rhyming, and filled with silly animal fun, Zzzookeeper is sure to become a new bedtime favorite.


"Cenko’s colorful illustrations, all full-bleed single- or double-page spreads, do a good job of capturing the rambunctious crew with amusing details..." - Kirkus Reviews
