New York Times-bestselling team Andy Griffiths and Terry Denton invite readers to come hang out with them in their 104-Story Treehouse―the eighth book in the illustrated chapter book series filled with Andy and Terry's signature slapstick humor!

Andy and Terry live in a 104-story treehouse. (It used to be a 91-story treehouse, but they decided it was still missing a few things.) It has a never-ending staircase, a burp bank, a deep-thoughts thinking room, Mount Everest, a mighty fortress reinforced with extra-strong fortress reinforcer, and a money-making machine (that also makes honey!).

When Andy has a toothache that hurts so bad he can’t write any jokes for their new book, Terry knows just what to do: buy a Joke Writer 2000™ to write the jokes for them! All they need first is some money from their money-making machine and then it’s off to the store. It’s a foolproof plan―a Terry-proof one, even!

What could go wrong?
