Captain Underpants and the Preposterous Plight of the Purple Potty People

The eighth book in Dav Pilkey's mega-bestselling Captain Underpants series. Now with super-cool foil covers! Shiny! Fun!When we last saw George and Harold, they were about to take their pet pterodactyl Crackers back to the Cretaceous period. But things didn't work out quite as they had hoped. They've entered an absurd alternate reality where teachers are nice, kids are allowed to read banned books, and the cafeteria food doesn't smell like dirty diapers. Even worse, they've discovered alternate versions of themselves--Evil George and Evil Harold--who plan to unleash some preposterous plans on Piqua, Ohio. Now it's up to George and Harold to defeat the evil twins and THEIR superhero, Captain Blunderpants!
