Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 1 is the 6th Captain Underpants book written by Dav Pilkey. The book starts with a demonstration day in class, where George and Harold show how to play a prank on people when they sit down on the toilet. Melvin then shows how he built a robot to combine two elements, demonstrating on Sulu the Hamster, but no one cares. Later, George and Harold also write a comic about Melvin, portraying him negatively and making him really mad. He goes home and tries to combine himself with a robot so he could become really powerful, but at the last minute, he sneezes, so he becomes a booger monster. One day, the class goes to a tissue factory, and Melvin is repeatedly offered tissues, making him really mad and starting to attack everyone. This was a job for Captain Underpants and Sulu the Bionic Hamster.
Dav Pilkey wrote a really amusing book. I like how he mentioned at the beginning that everyone can have a different kind of smartness and no one is actually “dumb”. It was also really funny with the way the school was portrayed after Melvin became the monster, because everyone needed umbrellas in the flu season. However, this book may not be ideal for some people because of the gross content mentioned. Because of all this, I give this book a four out of five.
