What’s it about?
The story.
Andy and Terry's treehouse has reached sixty-five storeys, with a pet-grooming salon, a birthday room where it is always your birthday, exploding eyeballs, a lollipop shop, a quicksand pit, an ant farm and, most importantly, a time machine. That last addition becomes vital when the treehouse fails its safety inspection and faces demolition. The boys are forced into a whirlwind trip through time, trying to fix the problem before their impossible home is destroyed. The fifth Treehouse book keeps the series' high-energy blend of words and cartoons, but the time-travel premise gives the chaos a particularly clear adventure shape. Terry Denton's illustrations make the historical jumps, silly rooms and disasters feel instantly readable, while Andy Griffiths' narrator voice keeps everything casual, loud and joke-driven. It is a strong pick for readers who like inventions, time machines and absurd problem-solving.

In the classroom
How it works in school.
The anarchic, hugely funny Treehouse series — a legendary reluctant-reader hook and classroom-library staple.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.
Why it lands
Why they love it.
Why kids love it
The specific kick is the time machine — the treehouse fails its safety inspection, faces demolition, and the boys race through history trying to fix the problem before their home gets knocked down. The Treehouse with the strongest save-the-treehouse engine.
- Adventure and freedom
- Having a secret base
- Secret world
- Trickery and cleverness
Why parents love it
The fifth Treehouse — time-travel hook gives this one a clearer adventure shape than most. Demolition-threat-to-the-treehouse plot is the kind of thing a series-deep reader feels in their stomach. Strong mid-series volume.
- Shared humour
- Quick to read
- Conversation starter
