Q&A with Andy Griffiths


Whats new for Andy and Terry in your latest book?

Well, we’ve got quite a lot going on in this one. It all starts when Terry leaves the door to the WHATEVER-WEATHER-YOU-WANT DOME open and a whole lot of wild weather gets out. Meanwhile the school truancy officer is trying to catch us and make us go to school.

And our evil twins Anti-Andy, Terrible Terry and Junkyard Jill escape from the doppelganger mirror to wreak havoc in the treehouse. And if that’s not already more than enough Mr Big Nose is yelling at us to get our book written … OR ELSE.


What can you tell us about the treehouse in your latest novel?

Well, apart from the weather dome and the hall of funhouse mirrors it also has a kangaroo-riding range, a paper-plane research and development facility, a gingerbread house, a monster level and a Santa Land where it’s Christmas all year round. Well, what are you waiting for? Stop reading this dumb interview and come on up and join us!


Whats your favourite invention in the treehouse?

Hmmmm … that’s a tough one. Maybe it’s our new potato-powered translation transmitter, which enables you to talk to anyone or anything no matter whether they are animals, vegetables or minerals. Have you ever talked to a rock?

Well you can with our new PPTT … but you will have to supply your own potatoes because we keep running out. (There are just so many things to talk to!)



What was your favourite part of writing this book?

Writing the words, THE END. Well, that was fun because it took us a whole 12 months to write the book, but maybe my favourite part was writing the whole ending sequence. I can’t tell you what it is because that would spoil it for it for you, but trust me, it’s the best ending to any book ever!

This is the last book in the Treehouse series – how does it feel saying goodbye?

Terry, Jill and I have mixed feelings. We’ve spent the last 13 years creating Treehouse books and we’ve loved – and laughed through – every silly chapter, nutty character and unlikely event. But just as it’s important to know how to start a story, it’s also important to know when to end it and we just felt it was time to let the fictional Andy, Terry and Jill move on and have their own adventures without us.

So we’re a little bit sad, but at the same time, really happy and proud that we managed to write 13 very silly books!


What are you working on next?

A complete guide to every character, every level and every invention in the treehouse. It’s called ‘Who’s who and what’s where in the treehouse’ and will be published November 2023.
