Andy and Terry's amazing treehouse has 13 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 a light-up dance floor, the world's scariest roller coaster and a top-secret 39th level which hasn't even been finished yet! But what good is all this stuff when Andy and Terry are trying to write their fastest book ever?

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!
