Titles in this Set: 1. The 143-Storey Treehouse 2. The 156-Storey Treehouse 3. The 169-Storey Treehouse Description: The 143-Storey Treehouse Andy and Terry have added thirteen new levels to their treehouse! There's a word-o-matic (it knows every word in the whole world!), a recycling depot, a wrecking ball, a deep, dark cave with a real live, fire-breathing dragon, a complaining room, a spooky graveyard (where it's always midnight, even in the middle of the day) and a camping ground where you can have a nice, relaxing camping holiday. But it turns out to be not quite as relaxing as Terry originally planned . . . Terry forgets to pack the tent and the food, their attempt at fishing ends in disaster, the spooky campfire stories are a little too spooky and then, to make matters worse, all of Andy’s fellow campers start mysteriously disappearing! Can Andy brave the dark, dark woods and rescue them in time to finish writing their next book? The 156-Storey Treehouse Andy and Terry have added 13 new levels to their treehouse! There's a wishing well, a world-record breaking level, a TV quiz show (hosted by Quizzy the Quizzical Quizbot) and an amazing mind-reading sandwich-making machine! But it’s the night before Christmas, and things are not going well for them – they’re at war with an angry snowman, Santa has crashed his sleigh and fallen into the cloning machine, and Mr. Big Nose wants a new book by tomorrow! Can they defeat the snowman, save Christmas, and get their book written in time? The 169-Storey Treehouse Andy and Terry have added thirteen new levels and built their biggest and most astonishing treehouse yet! It has everything they – and you – could wish for including: an electric pony stable, a NOISY level, a weather dome (where you can have whatever weather you want whenever you want it), and an 100% edible gingerbread house and a potato-powered translation transmitter that allows you to talk to everything everywhere all at the same time. There's also a hall of funhouse mirrors, which is the perfect place to hide from Mr Bunkoff who is trying to catch Andy, Terry and Jill in order to send them to school. But Anti-Andy, Terrible Terry and Junkyard Jill, their trouble-making opposites, are trapped in one of the mirrors — and they want out. (Oh, and Mr Big Nose wants them to write their book . . . RIGHT NOW.) Can our heroes escape school, defeat their doppelgängers AND meet their book deadline?
