However, the boys get their revenge by modifying things around in the teachers' lounge and after the field trip, the teachers get largely covered in glue and foam pellets before Ms. Ribble makes it even worse . They chase the boys around the school and after seeing the teachers looking like abominable snowmen, Mr. Fyde retires, thinking he's going insane . Meanwhile, Professor Poopypants sees an ad to teach and applies for the job, thinking children to be kind and sweet - hearted, but only gets them interested by building a robot that makes gerbils jog along with them . Some time later, Ms. Ribble reads the Pied Piper of Hamelin, which inspires George and Harold to make a comic about the Professor trying to take over the world, which destroys the last of Professor Poopypants' sanity . He makes the gerbil machine as large as a tall building, then shrinks the school and holds them hostage to turn their names sillier, with a system of 3 alphabetical name charts based on the first / last letter of each part of a first and last name . George and Harold's names are changed to "Fluffy" and "Cheeseball" respectively . They get Captain Underpants to steal Professor Poopypants' enlarging machine, but he and the machine are shrunk in the process .

"Fluffy" enlarges Underpants to the gerbil's size, then he defeats Professor Poopypants and everyone's names revert . The boys use the machines to bring the school and Captain Underpants back to normal size . Captain Underpants is soaked with water, turning him back into Mr. Krupp .
