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!

Tra-la-laaa! Captain Underpants is back in an epic adventure that's the zaniest, funniest, outrageousest, and time-travelingiest yet!

When we last saw our heroes, George and Harold, they were under arrest and headed for prison. Then Harold foolishly uttered the fateful words "What could be worse than going to jail for the rest of our lives?" and changed the course of human history.

In this ninth epic novel, Dav Pilkey takes readers back in time to the carefree days of kindergarten, when the worst thing George and Harold had to face was NOT evil mad scientists or alien cafeteria ladies but a sixth-grade bully named Kipper Krupp, the nephew of their clueless school principal. And because George and Harold don't actually invent Captain Underpants until fourth grade, the two clever kindergartners are on their own—using their brains to beat the bully.

Hold on to your UNDERPANTS—the Captain is back!
