Plot

The book picks off where the last one left off, where Tippy was crushed by the zombie nerd from Book 9. However, a sign explains that Tippy wasn't really squashed, because giant evil zombie nerds are incredibly slow. So, Tippy goes off to a convenience store and buys a cherry cough drop and a new bow-tie. Then, Tippy olives a extra-large ketchup packet and buys that too. Tippy saves himself with the ketchup packet. He then travels four years ago and freezes Kipper, Bugg, Finkstein, and Loogie. Then, when Tippy's Slightly Younger version comes, Future Tippy tells him that he is there to stop him from scaring them. Then, he shrinks Slightly Younger Tippy. He then travels four years into the future, where George and Harold were getting arrested in Book 8. He then freezes the cops, and chases George, Harold, Crackers, and Sulu around town. The next day, George and Harold are still hiding from Tippy's robotic freezing pants. They then go to to to the school to save the two pets by traveling 65 million years ago and leaving them there. However, Mr. Krupp then gets mad that the two are running away from him while he is asking them to tell him why they are late to school. It then turns out that he is there with a box of curtains, because they keep on disappearing. When George and Harold reach the library, they lock the door behind them, so Mr. Krupp won't get in. However, Mr. Krupp begins to unlock the door with his keys. He then bangs on the Purple potty demanding that they come out. However, then, Tippy then appears again, and is about to freeze Mr. Krupp. However, when they go back in time, Mr. Krupp also goes with them. (As, he was standing too close to the Purple Potty.) Tippy then sends Tiny Tippy back in time when George and Harold were going in the Purple Potty. Tiny Tippy then learns that they're going to the Mesozoic era. He then tells his two selves the news, and the three Tippys go back 65 million years.

Meanwhile, 65 million years ago, George and Harold notice that Mr. Krupp is also there with them. Harold goes out to grab his hand, but then Tippy kicks the tree. The five are then knocked down and the Purple Potty is then destroyed. George, Harold, and Mr. Krupp are saved by Crackers and Sulu. However, Mr. Krupp does not know this yet. Then, Tippy threatens to kill George and Harold. So the boys snap their fingers at Mr. Krupp, turning him into Captain Underpants. As Tippy chases the five, Tiny Tippy and Slightly Younger Tiny Tippy go back in time to chapter 8 of book 9 to get the Goosy-Grow 4000 from the top half of their suit so that way they can grow bigger than big Tippy, who the two think is a jerk. Slightly Younger Tiny Tippy then zaps Tiny Tippy and turns him into Supa Mega Tippy. Then, Supa Mega Tippy betrays Slightly Younger Tiny Tippy, who climbs onto his suit as a stowaway. He then goes back 65 million years ago when Big Tippy captures Captain Underpants, who up until then thought that they were playing chase. Big Tippy then falls into a lake, turning Captain Underpants back into Mr. Krupp. Just then, Supa Mega Tippy and Slightly Younger Tiny Tippy arrive. Tippy then tells the two that Captain Underpants' weakness is water. However then, Supa Mega Tippy then tells Big Tippy that HE is going to destroy Captain Underpants, not him. Out of anger, Big Tippy sets off his nuclear bomb. But Supa Mega Tippy kicks him into another part of the world. However, the bomb still blows up, killing the all the dinosaurs. The six then travel to a time about 200,000 years ago, when cavemen first existed.

Supa Mega Tippy then captures George, Harold, Crackers, and Sulu. Sulu then tears a hole through Tippy's robotic hands, and the four friends fly off, promising Mr. Krupp that they'll come back for him. Tippy then holds Mr. Krupp hostage until further notice.

Meanwhile, the four friends travel over to a cavepeople village, asking for help. However, they don't understand their accent. Tippy then attacks the village, forcing them all to seek refuge in a cave. George and Harold then write a wordless comic book on the cavewalls showing them how to defeat Tippy. After they finish reading it, they all start drawing out plans. Eventually, they each know what there is to be done. They then set up taps for Tippy and even burn up his robot pants. And when he fires the Freezy-Beam 4000 at the cavemen, Slightly Younger Tiny Tippy tampers with it so it won't turn off. Tippy tries his hardest to turn it off, but the emergency shut off is stuck. The ice spreads throughout the destroyed village quick, and into the mountains. Slightly Younger Tiny Tippy then steals the Goosy-Grow 4000, and zaps himself to a range of 120-150 feet. As he is about to reach 200 feet, the Goosy-Grow 4000 then falls on the ice, spreading it throughout the world.

George, Harold, Crackers, Sulu, and the cavemen run over to Mr. Krupp to free him. However, the ice encases over everyone and freezes them. When all hope seems lost, Tippy, now 200 feet tall, grabs everyone with his robotic hands. Then, George and Harold snap their fingers again, turning Mr. Krupp back into Captain Underpants. Captain Underpants rips off Tippy's robotic pants, leaving him standing there in his boxers. Using the pants as a net, Captain Underpants, George, Harold, Crackers, and Sulu take to cave people over to France, giving them a new place to live. When they return to Tippy, asking for a ride back to the future, Tippy squirts water from the water bottle at Captain Underpants' face, turning him back into Mr. Krupp. While they are all falling, Crackers is getting sicker and sicker for some strange reason. Tippy then captures the five with his hand, and they all get ready to go back home.

About 200,000 years later, the five notice that they're home. As they are celebrating, they notice that everything looks so old. Then Tippy tells them that he will not hurt them, but is going to destroy Captain Underpants, and that's why he brought them thirty years after the present, so that way the world doesn't have to get destroyed. He then lets George and Harold go. Crackers is continuing to get sicker, so Sulu makes him a nest. Then, the watch as Tippy tosses Mr. Krupp around with his foot, laughing maniacally. Then, the two discover that they're teachers in the future, but they're not very nice. So they make a vow to always be themselves. After that, they disappear, leaving old Mr. Krupp standing there confused. Then, they snap their fingers at him, telling him to save the present Captain Underpants. He does what he is told, and when he brings Captain Underpants back down, George and Harold snap their fingers, making TWO Captain Underpantses. They each beat up Tippy and his giant robo-boxers, but Tippy then sets off his nuclear bomb. Tippy then states to the six that the bomb will destroy the entire galaxy, as it is more powerful then a supernova. Suddenly, Crackers and Sulu sacrifice themselves by sending themselves back 13.7 billion years ago. When the three go back, the bomb explodes, causing the Big Ka-Blosh theory, incinerating Tippy and creating the universe.

13.7 billion years later, George, Harold, and Captain Underpants are stuck in the future without a time machine. Then, Harold points out that Crackers is a girl, because she laid three eggs. The three then decide to take care of the eggs, seeing as Crackers did something for them, so in return, they'll do something for HER. As the three are walking through town, Melvin appears in an octopus suit, and takes them to the present, telling them that something bad has happened since they've been gone.

Goofs

Tippy has his Shrinky Pig 2000, and Goosy Grow 4000, though in the fourth book, George and Harold take them, and put them in their treehouse.

Compared Events of time in Reality & the CU universe

Reality CU Universe
The universe began when a major atom formation that appeared then exploded 13.7 billion years ago Crackers, Sulu & Slightly Younger Tiny Tippy went back 13.7 billion years ago, where then a giant Thermoulnuclear bomb exploded, thus originating their universe!
The dinosaurs got killed when an asteroid that simotainsly fell from space hit the earth in Arizona 65 million years ago Supa Mega Tippy Kicked Big Tippy over into the Gulf of Mexico, where his bomb exploded at massive force precisely 65 million years ago
Art was started by the previous evolution period before Homosapians & became a natural thing of man since George & Harold showed early man how art was done, especially how to defeat Tippy
Harsh weather patterns 200,000 years ago set climates at a freezing standing, thus beginning the last major ice age in north America Tippy's parodoxes sabotaged his Freezy-Beam 4000 which then rapidly froze the area around, then expanded when the Goosy-Grow 4000 aimed directly below.
Mans nationalities formed in different kinds as they migrated and settled in different continents Almost every sub-race of humanity delled in the Americas, Until the ice age came by, thus they moved to Afro-Eurasia, to a cave in southern France.

Trivia

  • This is the final appearance of Sulu and Crackers as they sacrificed themselves to stop Tippy Tinkletrousers from using his bomb to destroy George, Harold, and Captain Underpants. It is also the final appearance of Tippy Tinkletrousers as he is killed by his own bomb.
    • This is also the first time good characters have been killed off in the series.
  • Crackers is confirmed to be female in this book as she laid three eggs before she and Sulu sacrificed themselves.
  • Despite what the 9th book said, this is not the final book of the Captain Underpants series.
  • This book shows three predestination paradoxes as Tippy was responsible for the extinction of the dinosaurs, the Ice Age, and the creation of the universe. Another predestination paradox was George and Harold creating the first cave drawings.
  • Melvin Sneedly makes a cameo for this book, and will appear in book 11, possibly having a major role.
  • This book is the second longest story in the series by far, having 224 pages. The longest being book 9, with 304 pages.
  • In chapter 8, the two Tiny Tippys go back to when Captain Underpants was battling Tippy in book 9. However, this is a flaw because Tippy made that battle never happen, and therefore, the top half of the suit never existed. In book 11, it might discuss why.
  • This book confirms that George and Harold will become similar to the teachers they are used to if they ever vow to change their ways.
  • In the chapter: Let's get serious folks!, some kids in the classroom are pretending to not enjoy reading the book, a girl in the middle bottom of the second page is flipping a Flip-O-Rama section that resembles a section in the book.
