Maybe I would recommend it to others. It's about Andy and Terry who go off on an adventure and they live in a 13-storey treehouse.

I think this book was really good because it's very funny and silly. I loved all the fun adventures Andy and Terry had in their treehouse.

My favourite character is Terry.
They do a drawing competition and he ends up getting hit with a giant banana.

It’s a fiction book. And in it there is a disaster: a monster mermaid tries to eat them, but they got the banana shrinker and shrunk it so small you could barely see it.

This is a very funny fictional story book. It's about a treehouse that has 13 levels. It was built by the main characters, Andy Griffiths and Terry Denton. They are good friends who fight a lot as well, a bit like my friends and I. I like Terry a lot because he is very funny and he taught snails to be ninja. I definitely recommend this book and the whole series of books to children who like funny fictional books.

It's a fiction, it's really funny. Because Terry kissed a mermaid and they got married, but actually the mermaid was a se monster the wanted to eat him.

This book is total chaos but the reason why I like this book is because there'll be always a happy ending

It’s fiction. My favourite character as Jill because she loves animals and I love animals and she has at least one of every animal on the planet

In this book the characters are called Terry and Andy. Terry kissed someone called mariadia and she transformed into a mermaid but she was a sea monster and Andy took pictures of mariadia in her sea monster body and showed it to Terry and he new then mariadia new as well when she came in to the marshmallow room.

15 Aug 2025

My favourite bit was when Terry flew with a bubble gum bubble.
My least favourite was when Terry and the mermaid done a big , fat kiss. I highly recommend this book

14 Aug 2025

Terry & Andy are so funny!

13 Aug 2025

I really like this book as it is very funny and I like the way it changes throughout the book and does not really have a main story. This means that you get to enjoy different tales within the one book.
Terry is my favourite character because he is very funny and I liked it when he bought a sea monster instead of a sea monkey

12 Aug 2025

I liked it when Terry married a sea monster because he thought it was a mermaid!

06 Aug 2025

I like the 13 story treehouse because it is really funny book and the illustrations are great even though they don’t have colour. It is a good book to start reading bigger chapter books. Once I had read the first page I knew I would like it and I did and the rest of the series.

05 Aug 2025

Very clever and exiting book!

05 Aug 2025

Funny, silly but I loved it!

04 Aug 2025

Really funny, I like the monkeys. I wish I lived in that tree

04 Aug 2025

This is my favourite book of the Treehouse series because they added funny things from hitting bananas to getting eaten by man eating sharks and also from concentrating on a ridiculous book such as this.

03 Aug 2025

The bit where the (not a) sea monkey ate all the food was hilarious

02 Aug 2025

I love the fact that it was funny.

01 Aug 2025

I really liked it a lot ! My favourite chapter was Chapter 7: Monster Mermaid!
I was very happy when Andy and Terry shrunk the sea monster!
