The 39-Storey Treehouse is the third book in Andy Griffith’s and Terry Denton’s wacky treehouse adventures, where the laugh-out-loud story is told through a combination of text and fantastic cartoon-style illustrations.

‘The kind of book I would have loved as a kid’ – Tom Fletcher, author of The Danger Gang

Andy and Terry’s amazing treehouse has thirteen new levels! It used to be 13 storeys, then 26, but they keep expanding!

They’ve added a chocolate waterfall you can swim in, a volcano for toasting marshmallows, a bulldozer-battling level, a baby-dinosaur-petting zoo, a not-very-merry merry-go-round, a boxing elephant called the Trunkinator, an X-ray room, a disco with light-up dance floor, the world’s scariest roller coaster and a top-secret thirty-ninth level which hasn’t even been finished yet!

And this year Terry has created the greatest invention that he—or anyone else—has ever invented . . . a Once-upon-a-time machine that will write and illustrate their entire book for them!

Well, what are you waiting for? Come on up!

Climb more fun-filled levels by collecting all thirteen books in the seven million-copy-selling series – the perfect chapter books for reluctant readers.

Professor stupido is my favourite character because he is so stupid and silly

I really like this fiction book as it is very funny. My favourite character is Terry because he is funny and good at drawing. My favourite moment in the book was when the 39th storey treehouse got un-invented and Terry and Andy had to go to Jill's house and sleep with all the animals.

Soo good

They have to sleep in a bed with all of Jill animals and it is very uncomfortable

They went on a moon trip to the dark side and they went to meet an inventor called Professor Stupido. Terry and Andy wanted to see if Professor Stupido could uninvent their once upon a time machine because it had hands and it wouldn’t let them get back in their own treehouse. I gave this book five stars because it was adventurous and funny.

My favourite treehouse book so far!

I like the wrong counting rocket from Andy. For example he counts like 6 8 9 4 3 10 1 5 7 2. It makes me laugh!

I enjoyed this book because it was really funny. I liked how the once upon a Time Machine locked them out of the treehouse.

Professor Stupido was very funny when he uninvented everything, but very silly when he uninvented himself!
