In our last epic adventure, George and Harold saved the world from the ridiculous Robo-Boogers, with the help of their newfound pterodactyl friend Crackers. Now, using Melvin's time machine, they head off to prehistoric times to return him to his own time. Unfortunately, due to their not following Melvin's direction, they're hurled into a strange alternate universe where everything is topsy turvy! The teachers are nice, the students are mean, and everything is out of whack! Even the great Captain Underpants has an alternate: the evil Captain Blunderpants! And when the alternates find their way to the non-alternate world, trouble, of course, commences.
The action is all-out this time around: mutated bionic hampsters, evil twins, elderly superheroes...this book has it all. It's amazing how Dav can continually top himself book after book. The humor is at it's peak, as is the action, and by the end, you'll be begging for more. Unfortunately, that "more" has no signs of showing up soon, but we'll certainly be on the lookout. We need you, Captain Underpants!
