The 104-Storey Treehouse

In the eighth book of the Treehouse series, Andy and Terry have expanded their treehouse to 104 stories, adding new features like a never-ending staircase, a burp bank, and a mighty fortress. When Andy's toothache prevents him from writing jokes for their new book, they come up with a plan to buy a Joke Writer 2000™ machine using money from their money-making machine. But as their adventure unfolds, things don't go quite as planned. The book is filled with the series' trademark slapstick humor and invites readers to join in the fun and chaos alongside the New York Times-bestselling duo.
