First published 2014
Andy and Terry have outdone themselves. Their treehouse now towers thirty-nine stories high, packed with thirteen brand-new floors of impossible contraptions. Andy bounces on the world's tallest trampoline while Terry roasts marshmallows over a real volcano. They plunge through chocolate waterfalls and pet baby dinosaurs that shouldn't exist. The Slurfinizer wraps its trunk around visitors for guided walks. A propeller-powered swivel chair launches them through the air. The scary roller coaster tests their courage on every ride. But the real surprise waits in Professor Stupido's laboratory, where the world's greatest UN-inventor creates devices that do exactly the opposite of what they should. Every floor brings new chaos. Every invention sparks fresh adventures. The treehouse keeps growing, and so do the possibilities for mayhem.
