Captain Underpants and the Preposterous Plight of the Purple Potty People is the eighth Captain Underpants book written by Dav Pilkey. At the end of the previous book, George, Harold, Sulu and Crackers time-traveled again. In this book, they come to a place that they realize is an alternate reality where everything is the opposite. They see evil George, evil Harold and evil Captain Underpants, who hypnotize Sulu to make him evil. George, Harold and Crackers try to time travel back to reality, but the evil people come with them. Once back home, evil George and evil Harold use the Goosy-Grow 4000 to increase Sulu’s size. Sulu then rampages across the city, destroying everything in its path. Will the good guys win, or will evil take over their reality?
This book was fascinating as it is still a continuation from the previous book. It was interesting to read about the alternate reality and how they got transported using a time machine, making the book seem like fantasy-science fiction. As always, I was laughing a lot while reading some parts of this book! Because of all this, I give this book a five out of five.
