The 39-Storey Treehouse

Laugh-out-loud wacky adventures in the world's MOST AWESOME treehouse! The third instalment in this hilarious and highly illustrated series will appeal to fans of Captain Underpants and Wimpy Kid.
Andy and Terry's amazing treehouse has thirteen new levels! They've added a chocolate waterfall you can swim in, a volcano for toasting marshmallows, a bulldozer-battling level, a baby-dinosaur-petting zoo, a not-very-merry merry-go-round, a boxing elephant called the Trunkinator, an X-ray room, a disco with light-up dance floor, the world's scariest roller coaster and a top-secret thirty-ninth level which hasn't even been finished yet! But how can they enjoy all this brilliant stuff when they have to write a book faster they've ever done before? You'll have to read it to find out!

The 39-Storey Treehouse is the third book in Andy Griffith's and Terry Denton's wacky treehouse adventures, where the laugh-out-loud story is told through a combination of text and fantastic cartoon-style illustrations.
