The tenth book, Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers, continues the time-traveling chaos. After Tippy Tinkletrousers’ latest scheme, George and Harold find themselves traveling through time, from the Ice Age to the dinosaur era, as they try to stop him from changing history.
I’d give this book a five out of five because it’s full of wild, imaginative adventures that take the series to new, unexpected places. The prehistoric setting and outlandish action make it a standout entry in the series, offering nonstop laughs and excitement. The creativity of the time-travel story, combined with hilarious encounters with dinosaurs and woolly mammoths, adds to the book’s charm. Pilkey’s illustrations are as fun as ever, and the flip-o-rama sections bring the action to life in a playful way.
