The Adventures of Ook and Gluk: Kung-Fu Cavemen from the Future is a graphic novel by Dav Pilkey and a second spin-off of Captain Underpants. Pilkey uses "George Beard" as the author and "Harold Hutchins" as the illustrator. These are the names of his characters in the Captain Underpants books. The plot of the book involves George and Harold, the lead characters from Pilkey's Captain Underpants series, complaining that scientists don't know everything, so they make a comic book about science facts.
Plot
The book begins with a scientific disclaimer by professor Gaylord M. Sneedly, saying that the book "contains many scientific errors and stuff." He stated that dinosaurs and cavemen did not live at the same time, as dinosaurs lived 64 million years before cavemen. He then stated that he should know about it, since he was a recipient of "The Most Brilliantest Science Guy of the Whole Wide World Award" in 2003, a reference to the seventh Captain Underpants book. However, George Beard and Harold Hutchins refutes this. They said that scientists make theories based on evidence they discovered, and that everyday, all kinds of evidence are being discovered. They also mentioned that they have a time machine, and been time traveling to the future and past, discovering lots of evidence that scientists did not have knowledge about, including dinosaurs and cavemen living at the same time. George and Harold stated that "scientists won't discover that until 2073." So they made "the world's first book based on science facts".
Plot
In Cave-land Ohio, 500,001 BC, the tribal leader of Cave-land, Big Chief Goppernopper, forces Gak, the older sister of Ook, to marry him in order to keep Ook and Gluk from bothering him. After saving her from a sandpit, the two Cave-kids befriend one of the dinosaur species Mog-Mog and her baby, and stop the wedding. Angered, Goppernopper walks away until he meets his descendant, J.P, who is the CEO from 2222 A.D. The Goppernoppers steals natural resources from caveman days through a time portal, since natural resources will be used up by that year. Ex-Chief goes back to the past and forces every cave-person in Cave-land to belong to the Goppernopper Enterprises. The Cave-kids and the baby Mog-Mog are shoveling until the Goppernoppers take them to 2222 to torture them, but the baby helps them escape and the three hide in Master Wong's School of Kung-Fu. Ook and Gluk grow up, training under Master Wong for 7 years, but the cave-kids have to give the right answer: "Who is the greatest man?" When it's time to save their people, they finally answer: nobody. Wong finally awards them black belts. They and their dinosaur buddy Lily travel back to caveman days and free the slaves. Goppernopper returns and orders his Mecha-saurs to attack the cave kids and dinosaur, but they spray-paint on the Enterprises building, then an explosive tank, which also destroys the Mecha-saurs themselves. Goppernopper sends them a letter, that Wong and Lan will be executed if the kids won't surrender. Back to 2229, Ook and Gluk plead with the Goppernoppers that they will do anything to satisfy them and they handcuff the three, but vows to execute them all. Wong tells them to remember their training, then, when J.P prepares his ray, the Cave-kids ask: Who is the greatest man? J.P and Chief answer themselves and their argument eventually makes J.P. shoot Chief, which accidentally erases himself and his damage on the world from history. The Cave-kids and Lily run back to the disappearing portal, but Ook soon returns for Lan, who agrees to be his cave wife and they warp back together, while 2229 receives a brighter and peaceful future. Lily finally re-unites with Her Mother, while the Cave-kids, Lan and the dinosaurs return happily to Cave-land.
