Andy and Terry''s amazing treehouse has thirteen new levels! It used to be 13 storeys, then 26, but they keep expanding!
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!
And this year Terry has created the greatest invention that he―or anyone else―has ever invented . . . a Once-upon-a-time machine that will write and illustrate their entire book for them!
