While Zookeeper is taking a nap, Walrus escapes from the zoo and takes the opportunity to explore the city. With Zookeeper hot on his heels, Walrus comes up with a series of clever disguises to keep hidden. Is there something strange about that mermaid in the fountain? And how about that last builder on the end – could that be Walrus?

This wordless picture book is a lot of fun with its colourful, retro illustrations and the antics of the cheeky aquatic hero. You wouldn’t believe how many places there are to hide a walrus in the city!
