Captain Underpants and the Tyrannical Retaliation of the Turbo Toilet 2000
Book 11 of 12 in Captain UnderpantsView the full series
A return to one of the series' signature villains: the Turbo Toilet 2000. It is more straightforwardly silly than books 9–10, with big potty-power action and familiar gross-out superhero parody.

What’s it about?
The story.
George and Harold thought their toilet troubles were over when the Turbo Toilet 2000 was defeated. Unfortunately, the carnivorous commode is back, and this time it has a very big appetite for revenge. Captain Underpants must once again take on a monstrous toilet in a showdown of Wedgie Power versus Potty Power. The eleventh Captain Underpants book returns to the kind of absurd villainy that made the early books so memorable, while still carrying the later-series confidence and scale. It is full of toilet jokes, comic action, fake science and exaggerated danger. For adults, it may be exactly the sort of book they fear children will love. For many children, that is its magic: it treats their silliest sense of humour as a valid reason to read.

In the classroom
How it works in school.
The anarchic, wildly funny Captain Underpants 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 original talking toilet from book two — the one a child has probably half-forgotten — comes back as an enormous mecha-version of itself and tries to eat the school. The recognition moment is the whole point. Children who remember the first Flip-O-Rama find a callback they didn't know they wanted.
- Breaking the rules safely
- Revenge on adults
- Surviving danger
- Making a difference
- Friendship and belonging
Why parents love it
The callback book — the antagonist a child first met in book two returns vastly bigger. Best for a child who's read books one to two recently enough to feel the joke. Not a starting point, but a confident late-series volume that knows exactly who's reading it.
- Shared humour
- Quick to read
- Nostalgia
