Little Tiger is celebrating the 10th anniversary of the hilarious Poo in the Zoo series, written by Steve Smallman and illustrated by Ada Grey, with a brand-new sixth adventure called Poo in the Zoo: Unicorn Poo.
Commissioning Editor Perry Emerson acquired world rights, all languages, for the text from Tormenta Illustration and Literary Agency. Illustration rights were acquired from Jodie Hodges at United Agents.
Bob’s McGrew’s zoo gets a flamboyant, superstar make-over in the sixth instalment of this poop-tacular series.
Rose the unicorn is a superstar – flamboyant, fabulous and . . . a real demanding diva. The other animals try their best to make her feel welcome, but soon Rose is making everybody miserable with her never-ending list of demands. Will everything change when Rose rushes to do a poo? Could this be . . . the doo-doo of their dreams?
To further celebrate the 10th anniversary of the series, Little Tiger is also re-issuing the original books with new shiny foiled covers.

What a joy to be celebrating 10 years of Poo in the Zoo! Steve and Ada are a dream bookmaking duo, pairing Steve’s inexhaustible capacity for witty rhyme with Ada’s endless delight in illustrating even the silliest of poo jokes. Their innate sense of what makes children laugh creates books that readers reach for again, and again, and again. We are excited to continue to build on the success of this poop-tacular series with a fabulous new story featuring a not-so-fabulous unicorn and a bold new cover look for the brand.

I can’t quite believe that it’s ten years since Poo in the Zoo was first published! The lovely people at Little Tiger gave me the title and an open brief, what a gift! I had such fun writing it, trying very hard to make a story about poo sweet and funny. All the poo without the ‘Ewww!’
Ada Grey’s charming illustrations have brought Little Bob McGrew, Hector Gloop, Arabella Slater and all their animal friends to warm and wonderful life and children across the world seem to have taken them to their hearts!
Seeing little children dressed as Bob or Hector on World Book Day makes me so happy! Their latest adventure, (the sixth book in the series!) features Rose, a unicorn who may not be quite as fabulous as she seems! I loved writing it, I hope you love it too!

I am so happy to be celebrating ten years of Poo in the Zoo! Steve Smallman and the fabulous team at Little Tiger are a pleasure to work with, and Unicorn Poo really is a joy. With all the usual silliness of poo, and the glamour of a Unicorn with several surprises along the way, it’s been so much fun to work on!
Little Tiger will publish Poo in the Zoo: Unicorn Poo in June 2027.

Ada was lucky enough to grow up in a family run bookshop, and inheriting her mum’s doodling ability, has been an illustrator for an embarrassingly long time. She lives on the south coast in the UK with a wild teenager and a tame tom cat, and is also a professional gardener.
