Treehouse Companion Books in Order

The Treehouse companion books sit beside the main novels and let readers linger in Andy and Terry's world a bit longer. Instead of following one big plot, they offer activities, jokes and bite-sized stories that you can dip into whenever you like.

The Treehouse Fun Book and its sequel are packed with puzzles, drawing prompts, word games and make-your-own-level challenges. Kids are invited to design new treehouse floors, decode secret messages, invent strange ice-cream flavours and scribble all over the pages in the same anarchic spirit as the series itself.

The Treehouse Joke Books gather hundreds of gags, puns and one-liners sorted by theme, from animals and pirates to school and space. Some jokes are borrowed from the novels, others are brand new, but they are all short, silly and easy to share aloud with friends or classmates.

Tales from the Treehouse collects short stand-alone adventures that did not quite fit into the numbered books. These stories feel like extra episodes: surreal little side quests where Andy, Terry and Jill explore new levels, run into odd visitors and follow throwaway ideas to ridiculous extremes.

Shorter titles such as Ten Unlucky Pirates and Terry's Dumb Dot Story rework favourite episodes from the larger novels into slim, full-colour stories for beginning readers. They keep the big energy of the treehouse but shrink the text and page count so newer readers can manage them independently.

Taken together, the companion line is less about strict reading order and more about giving fans different ways to play. They are great for car trips, classroom libraries and rainy afternoons, and they double as a gentle bridge between picture books, chapter books and creative writing of your own.
