Andy and Terry are once again inviting readers to come hang out with them in their astonishing 39-story treehouse (it used to be 13 stories, then 26 stories, but they keep expanding).

And this year they will have even more time to jump on the world's highest trampoline, toast marshmallows in an active volcano, swim in the chocolate waterfall, pet baby dinosaurs, and go head-to-trunk with the Trunkinator, since 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!


安迪和泰瑞再次邀請讀者跟著他們進入39樓高的樹屋故事裡。（原只有13層樓，後來增加到26層，之後不斷增加。）

今年跟著他們腳步一起跳世界最高的彈簧床、在活火山烤棉花糖、在巧克力瀑布裡游泳、照顧恐龍寶寶和 Trunkinator 大象一起玩耍。自從泰瑞發明了最棒、無人能敵的「很久很久以前」機器，這台機器可以為他們寫書並畫上插圖呢！
