The 156-Story Treehouse: Holiday Havoc!
(Treehouse Books #12)

New York Times-bestselling team Andy Griffiths and Terry Denton invite readers to come hang out with them in their 156-Story Treehouse--the twelfth book in the illustrated chapter book series filled with Andy and Terry's signature slapstick humor!

Andy and Terry live in a 156-story treehouse. (It used to be a 143-story treehouse, but they added 13 more levels.) It has a wishing well, a super-stinky stuff level, a bouldering alley (it's just like bowling, except you use boulders instead of balls), an enigma engine, a TV quiz show level hosted by Quizzy the quizzical robot, and the amazing mind-reading sandwich-making machine that knows exactly what sort of sandwich you want and makes it for you.

It's the night before Christmas but Andy and Terry aren't ready yet! They haven't written their letters to Santa, they haven't sung any carols or hung their stockings, and now Mr. Big Nose wants their next book done by tomorrow. When Santa Claus's sleigh crash-lands in the treehouse, the reindeer become tangled in the branches and Santa falls into the cloning machine. With dozens of Santas running around and no way to tell which one's the real one, who's going to deliver all the presents? It's up to Andy, Terry, and Jill to work together to save Christmas--and maybe even finish their book on time!
