"A basic yet complete presentation of how to plan, design, and build a safe, fun treehouse structure for children"--Provided by publisher.

Sam and Spider build a tree house and go there with Lolly to trade stories.

Join Andy and Terry in their now 91-storey spectacular treehouse (It used to be a 78-story treehouse, but they keep getting ideas for more stories!). They've added 13 new levels, including the world's most powerful whirlpool, a mashed-potato-and-gravy train and a human pinball machine. Why not try your luck on the spin-and-win prize wheel or hang out in a giant spider web (with a giant spider), or you can always get your fortune told by Madam Know-it-all...

Andy and Terry, introduced in "The 13-Story Treehouse", have expanded their incredible arboreal residence by adding several exciting features, including a robot-controlled ice-cream parlor, a mud-fighting arena, an ATM (Automatic Tattoo Machine), and the Maze of Doom. Their publisher, Mr. Bignose, is demanding their next book, so the friends attempt to tell stories about how they met and how they first built their treehouse. They also have to cope...
