New York Times-bestselling team Andy Griffiths and Terry Denton invite readers to come hang out with them in their 91-Story Treehouse--the seventh book in the illustrated chapter book series filled with Andy and Terry's signature slapstick humor!

Andy and Terry live in a 91-story treehouse. (It used to be a 78-story treehouse, but they keep getting ideas for new stories!) It has a submarine sandwich shop that serves sandwiches the size of actual submarines, an air-traffic control tower, a human pinball machine, a spin-and-win prize wheel, a giant spider web--with a giant spider!-- and a big red button, which they're not sure whether to push or not because they can't remember what it does.

Good thing there's so many fun things to do in the treehouse, because Andy and Terry get stuck babysitting Mr. Big Nose's three grandchildren for the day.

After all, how much trouble could they possibly get into in just one day?

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

"Twice the treehouse, twice the fun? You bet. . . . Denton's furiously scrawled line drawings milk the silly, gross-out gags for everything they're worth. Kids should be flipping pages faster than a pair of inflatable underpants can skyrocket the young heroes to safety." --Publishers Weekly, starred review, on The 26-Story Treehouse
