Andy and Terry live in the WORLD'S BEST treehouse! It's got a giant catapult, a secret underground laboratory, a tank of man-eating sharks and a marshmallow machine that follows you around and shoots marshmallows into your mouth whenever you're hungry! Just watch out for the sea monkeys, and the monkeys pretending to be sea monkeys, and the giant mutant mermaid sea monster . . . Oh, and, whatever you do, don't get trapped in a burp-gas-filled bubble . . . !

Andy Griffiths and Terry Denton's fantastically funny The 13-Storey Treehouse is told through a combination of text and cartoon-style illustrations.

In the media

Full of crazy, funny pictures, which will make you laugh . . . Extremely enjoyable, very funny and easy to read!
Especially good for reluctant readers as it is heavily illustrated and VERY funny . . . This really is the coolest treehouse ever!
Angels & Urchins
Longtime collaborators Griffiths and Denton (Killer Koalas from Outer Space) get metafictional in their latest book (first published in Australia), and the result is anarchic absurdity at its best... Denton's manic cartooning captures every twist and turn in hilarious detail, as babies are pelted with garbage, yapping dogs squashed, and monkeys catapulted into the distance. A sequel was published last year in Australia and can't arrive soon enough.
