The 104-Story Treehouse: Dental Dramas & Jokes Galore!

New York Times-bestselling team Andy Griffiths and Terry Denton invite readers to come hang out with them in their 104-Story Treehouse—the eighth book in the illustrated chapter book series filled with Andy and Terry's signature slapstick humor!
Andy and Terry live in a 104-story treehouse. (It used to be a 91-story treehouse, but they decided it was still missing a few things.) It has a never-ending staircase, a burp bank, a deep-thoughts thinking room, Mount Everest, a mighty fortress reinforced with extra-strong fortress reinforcer, and a money-making machine (that also makes honey!).
When Andy has a toothache that hurts so bad he can't write any jokes for their new book, Terry knows just what to do: buy a Joke Writer 2000™ to write the jokes for them! All they need first is some money from their money-making machine and then it's off to the store. It's a foolproof plan—a Terry-proof one, even!
What could go wrong?
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
