A lot or a little?

The parents' guide to what's in this book.

Educational Value

In addition to having strong vocabulary words, the story features DNA and the Higgs boson as part of the plot.


Positive Messages

If you make a mistake, keep trying. Being revered as a hero might not be as fabulous as you'd expect. Don't skip school.


Positive Role Models & Representations

George and Harold, exhausted from their time travel, do their best to cope with their obligations. They're loyal friends, and, although they would be perfectly content to stay out of school, they respect their scholarly obligations. The boys are good problem-solvers; they make some missteps, but they persevere. Authority figures are exaggeratedly mean and ridiculously power-mad.


Violence & Scariness

There's a fair amount of cartoon violence, mostly of a giant, toothy toilet wreaking havoc in the city. Nana and Timmy help out with a sanitized cartoon for the "Incredibly Graphic Violence" chapters.



Melvin calls Turbo an "idiot," and potty humor includes making fun of Uranus -- and, of course, there's a giant, rampaging toilet.


What parents need to know

Parents need to know that Captain Underpants and the Tyrannical Retaliation of the Turbo Toilet 2000 continues in the same vein as the rest of the series: lots of silly potty humor, but all pretty harmless. There's even some educational stuff in here -- discussion of Higgs boson, anyone? Teachers, convinced they're dreaming, strip down to their underwear and behave ridiculously, even "pantsing" a police officer. There are a few off-color jokes about Uranus, using a soda bottle as an emergency urinal, and a drawing of the Turbo Toilet's swollen bottom after a spanking. The realization that a hamster and pterodactyl have mated elicits an "ewwwwww." School staff are nastily delighted with a plan to split up best friends George and Harold.

What's the story?

George and Harold travel through time back to the present with Captain Underpants and Melvin, who is being strangely helpful. But Melvin has an ulterior motive: He wants Captain Underpants to deal with the resurrected Turbo Toilet 2000. Melvin had defeated him and relished his new role as a hero … except for all the interruptions from his own work to handle so-called emergencies. George and Harold, exhausted from their time-traveling adventures, make a major mistake at school and face being separated next year. So they decide to travel back to yesterday and undo the mistake. Now there are two Harolds and two Georges, a vengeful Turbo Toilet 2000 headed their way, and more chaos than even Captain Underpants can handle.

Is it any good?

This book definitely keeps up the manic chaos of the preceding 10 books in this giddy series. The crude humor -- Uranus jokes and teachers stripping down to their skivvies -- are likely to make parents' eyes roll, but it's irresistible to kids. This remains a great series to entice reluctant readers, and a welcome break for kids who also enjoy more, er, literary fare.

But this isn't just a dumb series. Dav Pilkey works the Higgs boson, genomes, and the implications of time travel into the convoluted plot. Less familiar words are well-supported with context clues and include "smoldering," "exoskeleton," "morphed," "swiveled," and "theoretically." Adults will appreciate the sneaky cultural references to Tony Orlando and Dawn, The Shining, Monty Python and the Holy Grail, and more.

Talk to your kids about ...

  • Families can talk about the appeal of potty humor. Would this book be nearly as funny if the Turbo Toilet 2000 were, say, the Turbo Trash Can 2000?

  • Do you think adults (such as Nana in the book) are appropriately concerned about violence in children's books, movies, and TV shows? How does the violence in this book compare with cartoons or movies you've seen?

  • Kids may want to try making their own comics or a flip-o-rama -- and grown-ups can get in on the fun, too.
