From the critically acclaimed author and illustrator of A Hungry Lion and Stumpkin comes a charming, wryly humorous story of adventure, mistaken identity, and a vampire family's day at the zoo.
On a Saturday morning, baby Dracula visits the zoo with his family, where baby Penguin lives with hers. But these intrepid young adventurers are not content with staying in their proper places.

Instead, baby Dracula slips into the Penguin House to spend the day eating, swimming, and hanging around, while baby Penguin waddles into the stroller to explore the rest of the zoo. Dracula's family doesn't even notice the switch—will they bring the right baby home?

Observant and adventurous young readers will love this tale of the shenanigans that happen when parents' backs are turned.
