Andy and Terry live in a 52-Story treehouse. (It used to be a 39-story treehouse, but they keep expanding.) It has a chainsaw-juggling level, a make-your-own-pizza parlor, a rocket-powered carrot-launcher, a life-size snakes and ladders game, a remembering booth, a Ninja Snail Training Academy and a high-tech detective agency, with all the latest high-tech detective technology, including the Disguise-o-Matic 5000! Something that is sure to come in handy as they try to solve the mystery of: What happened to Mr. Big Nose? After all, it's hard to turn in your next book when your publisher has vanished! Join New York Times-bestselling author Andy Griffiths and illustrator Terry Denton on another wild storytelling adventure in a series Publishers Weekly described as Anarchic absurdity at its best.
