Captain Underpants and the Perilous Plot of Professor Poopypants: Summary
As Captain Underpants and the Perilous Plot of Professor Poopypants begins, we are introduced to Professor Pippy P. Poopypants. The professor comes from a place where everyone is given silly names. He is brilliant and creates the Shrinky-Pig 2000, a shrinking machine shaped like a pig, and the Goosy-Grow 4000, an enlarging machine that appears like a goose. The brilliant professor travels to America to show off the machine. He plans to use it for good to decrease the world’s garbage and create a greater food supply. However, nobody will take him seriously because of his name.
Meanwhile, George and Harold are banned from a school field trip when Principal Krupp observes them altering a sign. Instead, they are instructed to tidy up the teacher’s lounge. As an act of revenge, the boys plan a prank that causes all the teachers to be sprayed with water, then covered in paste, and stuck with styrofoam. After the prank, the science teacher retires.
Discouraged by his unsuccessful journey to show off his invention, Professor Poopypants sees the open position at the school, mistakenly thinking the kids would be kinder and be able to look past his name. Once he is hired, he finds them to be just as bad as everyone else.
He succeeds in engaging the students when he creates a robot that lets a gerbil run with its master. However, when the student find out that the P in his names stands for Pee-Pee, they begin to make fun of him again.
When Geroge and Harold read the Pied Piper of Hamlin, they get the idea for their next comic. In it, Professor Poopypants becomes a teacher at the school, but becomes angry when he gets made fun of. He decided to make a Gerbil Jogger 2000 army, and when they won’t follow his orders he brainwashes them, forcing them to listen to Cher. All of the kids are taken hostage, but Captain Underpants comes to the rescue. Professor Poopypants turns himself into a giant robot when they continue to laugh at him. He fights Captain Underpants who eventually flushes toilet water over him, making him rust.
The comic makes everything worse for Professor Poopypants, destroying him and causing him to go insane. He uses his Goosy-Grow 4000 to make a giant gerbil machine. He gets inside and uses his shirking machine to shrink the school and hold everyone hostage. He demands that everyone will be given a silly name or will be punished by being shrunk. Professor Krupp becomes Lumpy Pottybiscuits, George becomes Fluffy, and Harold becomes Cheeseball.
George and Harold recruit Captain Underpants to steal the enlarging machine, but since he refuses to change his name, he is shrunk along with the machine.
The boys try to restore the size of the school, but fall off of it. They make enlarge an airplane made out of paper to fly. Captain Underpants rescues them. George enlarges Captain Underpants, and he fights and defeats Professor Poopypants. Everyone’s name returns to the original, and the enlarging and shrinking machines are used to return everything to their original size. Captain Underpants is changed back into Principal Krupp.
Harold and George suggest that Professor Poopypants change his name as he is taken to jail. He agrees, but picks the name Tippy TInkletrousers which only results in more ridicule in jail.
