13-Story Treehouse

In my house, we have almost all of the treehouse series. But today, I'm going to talk about the first book in the series, which is the 13-story treehouse. Basically, they add 13 more stories after the first book. In the first book, they introduce themselves and the treehouse. It's about Andy and Terry who has this cool treehouse and goes on adventures. They write their adventures in the treehouse into a book. The first adventure starts when Terry paints a cat. Literally paints a cat. Then the cat turns into a "catnary". Then, they find out that the cat is actually Jill, their friend's favorite pet. Then, Mr. Bignose, their publisher, calls them and tells them to finish their book.After that, the delivery man delivers the sea monkey. They find out that it's not a sea monkey, it's a mermaid! Terry falls in love with the mermaid. Then, Andy sees the mermaid transforming into a sea monster. He calls terry and they get rid of the sea monster. Andy then finds out that Terry delivered lots of sea monkeys and kept them in their lab. The monkeys destroys everything in the treehouse. Then, there's the big gorilla that's shaking the tree. Afterwards, the group of catnarys that Terry made comes to the rescue. They take the gorilla back where it belongs. Eventually, they decide to write a book about their adventure. They deliver it to Mr. Bignose in time, and ends in a happily ever after. This book is very fun, I recommend it if you haven't read it yet.
