Today's guest is an international Kid lit superstar! Together with illustrator, Terry Denton, he has built 143-Storeys of comedy mayhem that has sold over 10 million copies and is about to sell a few more.

That's right, the next Treehouse book is out today and it's an absolute ripping read. So, to tell us all about it and what it was like behind the scenes, please give a huge cheer for the amazing Andy Griffiths. Woo-hooo!

Hear what makes the treehouse so much fun. What it's like behind the scenes with Andy and Terry. And all the fun that makes the treehouse such a winner with readers.
