Barner’s straightforward primer about all things penguin is anything but pedagogical. In fact, the rhyming verse resembles more of a lyrical lesson (“Cold penguins huddle close with penguin heat to share./ Daddies warm fragile eggs with tender, special care”). At story’s end, a “Penguin Puzzler” reveals answers to some of the more confounding questions (“Why do penguins look the way they do?”), while a “Penguin Parade” identifies their many types and habitats. Whether or not readers are penguin aficionados to begin with, they will likely end up knowing more than when they started.
