My favourite character was Andy because Terry rolled Andy's head off and thought it was a bowling ball. Also, Andy thought Terry's finger was a fork.

The two main characters are Andy and Terry. They live in a 13-storey treehouse.In this book, Andy and Terry have to write and illustrate a book for Mr Big Nose to publish. But while they are making the book, they have some problems along the way.I thought the whole book was interesting and funny. I would recommend this book to other children because it is easy to read, fun and very funny.

I really didn't like the seamonster disguised as a mermaid. I liked it when Mr Big Nose's nose nearly exploded.

My favourite part of the story was when Terry bought sea monkeys and it was actually a mermaid, but when he went away, he didn’t notice that it was a slimy sea monster. Then both of them found out that it was a slimy sea monster, and they used the shrink ray to shrink the slimy sea monster and flush it down the toilet.
