Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 1: The Night of the Nasty Nostril Nuggets: Summary
Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 1 begins as George and Harold are demonstrating a new prank for a speech in school. They call it the “squishy”. It involves ketchup packets placed on the toilet seat so whoever sits down to use the toilet will end up with ketchup splashed all over them. The speech is well received, and everyone in the school including the teachers are eager to try it. However, Melvin Sneedly insists they listen to his presentation before they leave. He displays his newest invention the Combin-o-Tron 2000. To demonstrate how the machine works he takes his pet hampster Sulu, and a robot hamster and combines them with the machine, creating a bionic hamster. Melvin attempts to get Sulu to do tricks, but he refuses to obey. Melvin cries and says he no longer wants the hamster, so George and Harold adopt him.
Ms. Ribble plays the prank on Principal Krupp who believes George and Harold are responsible, even when she tells him otherwise. He then discovers that the entire 4th grade is giving and receiving the prank. Melvin tattles on George and Harold, explaining to Principal Krupp that they were the ones to teach the prank to everyone. Principal Krupp gives George and Harold detention, and they decide to write a comic about Melvin because they are so angry.
The comic revolves around a tattletale named Melvin who tells on everyone anytime they break a rule. Eventually, he tells on a group of robbers. He is a hero and becomes the youngest mayor in history. As mayor, he makes ridiculous rules and the jails fill up quickly. Melvin creates a robot called the Tattlletron 2000 to capture any lawbreakers. When Captain Underpants appears he is immediately captures, but he easily escapes. He devises a plan to fight to robot and free its captives. He feeds the robot prune juice, causing him to poop out the lawbreakers. Captain Underpants puts Melvin in jail and releases the remaining prisoners.
When Melvin reads the comic, he is angry. He decides to make a bionic version of himself to have superpowers like Sulu. He builds a robot with superpowers and plans to use the Combine-o-Tron 2000 to combine himself with it. Melvin sneezes at the last second and ends up part boy, part robot, and part mucus, resulting in Bionic Booger Boy.
As Bionic Booger Boy, Melvin is a star football player, volleyball player and has his own drinking fountain. When flu season comes, he sneezes huge amounts of snot and has a voice like a monster. On a class trip to the tissue factory, he destroys the factory to defend himself.
George summons Captain Underpants, and when he rescues his secretary, she kisses him turning him back into Principal Krupp. Bionic Booger Boy attacks George and Harold next, and they are saved by Sulu.
Melvin’s parents try to change him back to normal, and when they change the batteries in the Combine-o-Tron at George and Harold’s suggestion, it works. However, in the process he switches bodies with Principal Krupp. The booger globs fly off of Melvin and come to life, destroying the Combine-o-Tron 2000. The book ends as the boogers chase George, Harold, Prinicpal Krupp, Melvin, and Sulu.
Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy Part 1 includes controversial anti-authority themes and theme of good vs. evil and acceptance. As the boys are readily accepted by the school while they are demonstrating a prank for their demonstration speech, Melvin Sneedly is ignored as he attempts to show off his new invention. He later becomes their enemy and refuses to help George and Harold since they made him look uncool in a comic. Discuss the appropriateness of the behavior of the boys in this book, and how it is important that everyone feels accepted.
