The 117-Story Treehouse

New York Times-bestselling team Andy Griffiths and Terry Denton invite readers to come hang out with them in their 117-Story Treehouse—the ninth book in the illustrated chapter book series filled with Andy and Terry's signature slapstick humor!
Andy and Terry live in a 117-story treehouse. (It used to be a 104-story treehouse, but it just keeps growing!) It now has a pajama-party room, a water-ski park filled with flesh-eating piranhas, an Underpants Museum, a giant-fighting-robot arena, and the Door of Doom (don't open it or you'll be COMPLETELY and UTTERLY DOOMED!).
For as long as Andy and Terry have been writing books together, Andy has always been the narrator and Terry has always been the illustrator. But when Terry tries to prove that he can narrate as well as draw, the story goes completely out of control and the Story Police arrive to arrest the whole treehouse team for crimes against storytelling! Andy, Terry and Jill go on the run, but how long can they evade the Story Police and stay out of Story Jail?
Praise for Andy Griffiths and the Treehouse series:

"Anarchic absurdity at its best. . . . Denton's manic cartooning captures every twist and turn in hilarious detail." —Publishers Weekly, starred review, on The 13-Story Treehouse
"Will appeal to fans of Jeff Kinney and Dav Pilkey. . . . The wonderfully random slapstick humor is tailor-made for reluctant readers. . . . A treat for all." —Booklist on The 13-Story Treehouse
