Andy and Terry’s amazing treehouse has 13 new levels including a chocolate waterfall, a non-erupting active volcano, an opera house, a baby-dinosaur petting zoo, Andy and Terry’s Believe it or Else! museum, 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 39th level that hasn’t even been finished yet!
So what are you waiting for? Come on up!
One thing that can be said about the audiobook experience of the Treehouse series is that Stig Wemyss really enjoys his role as narrator, and with the freedom and challenge of engaging children in an audio book his enthusiasm is a great draw.
Despite this, I do think this would have been a good one to read rather than listen to, there sounds like there would be a great assortment of pictures based on what happens. That is to say it wasn’t still enjoyable. As before, audio prompts, music, and sound effects make this just as enjoyable, maybe even more so; though I do feel like Terry’s drawings are being neglected, considering how much he talks about drawing in the books.
With another 13 storeys added to the treehouse another adventure awaits. Andy tells us what new things they have added to the treehouse, each as exciting and improbably and delightful as the previous things. Andy and Terry once again have a book due but Terry has a solution he’s been working on which naturally causes mayhem.
Terry also got a spotlight moment and a reprieve from being the daft friend, his drawing skills become essential and his illustration skills are commended. There’re also songs in this story, some more poems than songs, but one definite song, which Wemyss has to sing which was…an experience. I’m also learning that there will always be a recap of the book within the book, but thankfully it’s a fast recap.
Griffiths certainly had worked out a rhythm with this series. It’s repetitive, cheeky, silly, and all the fun and gross (but not too gross) things that make kids laugh. Once you get used to the structure of these books they become quite enjoyable, no matter your age.

Seventeen-year-old Gwendolyn P. Pearson has become very good at not thinking about the awful things that have happened to her family. She has also become used to people talking about her dead mum. Or not talking about her and just looking at Gwen sympathetically. And it’s easy not to think about awful things when there are wild beaches to run along, best friends Loretta and Gordon to hang out with – and a stepbrother to take revenge on. 
Andy and Terry’s incredible, ever-expanding treehouse has 13 new storeys, including a watermelon-smashing level, a wave machine, a life-size snakes and ladders game (with real ladders and real snakes), a rocket-powered carrot-launcher, a Ninja Snail Training Academy and a high-tech detective agency with all the latest high-tech detective technology, which is lucky because they have a BIG mystery to solve – where is Mr Big Nose???
If you’re like most readers, you’re probably wondering just how Andy and Terry met. Well, it’s a long story, but a pretty exciting one, and it’s mostly true! Come on up, choose a hammock, and they’ll tell you all about it (just don’t go in the maze they’re still ironing out a few bugs…). 
Who wouldn’t want to live in a treehouse? Especially a 13-storey treehouse that has a bowling alley, a see-through swimming pool, a tank full of sharks, a library full of comics, a secret underground laboratory, a games room, self-making beds, vines you can swing on, a vegetable vaporiser and a marshmallow machine that follows you around and automatically shoots your favourite flavoured marshmallows into your mouth whenever it discerns you’re hungry.
