In this all-new graphic novel, George Beard and Harold Hutchins present the sensational saga of two silly caveboys named Ook and Gluk. Ook and Gluk have a pretty awesome life growing up together in Caveland, Ohio, in 500,001 BC--even though they're always getting in trouble with their nasty leader, Big Chief Goppernopper. But Ook and Gluk's idyllic life takes a turn for the terrible when an evil corporation from the future invades their quiet, prehistoric town. When Ook, Gluk, and their little dinosaur pal, Lily, are pulled through a time portal to the year 2222 AD, they discover that the world of the future is even worse than the devastated one they came from. Fortunately, they find a friend in Master Wong, a martial arts instructor who trains them in the ways of kung fu, so that they may one day return home and make things right again. And, like the other Captain Underpants books, "The Adventures of Ook and Gluk, Kung-Fu Cavemen from the Future" features the world's cheesiest animation technology, "Flip-O-Rama," in every chapter.
