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. Joining the fantastic Treehouse crew is Stig Wemyss who reads the story in the accompanying audio CD.
