When Great-Uncle Horace brings back lost and homeless animals from his travels around the globe, it falls to Zoe and her mum, the zoo's vet, to settle them into their new home.

Zoe's good at this, because she can understand what they say and talk to them, too.

But that's a secret! In this second book, a tiny penguin arrives at the zoo.

He's really cute, but a bit of a puzzle - he just doesn't seem to know he's a penguin!
