A collection of thirteen short stories from the world of the New York Times–bestselling Treehouse chapter book series.

International author-illustrator superstar duo Andy Griffiths and Terry Denton are back, and this time they've cooked up a hilarious book of thirteen standalone stories to complement their beloved chapter book series. Surreal, funny and supremely silly—all with the spirit of the Treehouse.
