While the kids are at a beach, George and Harold create a comic book.

"Captain Underpants and the Sickening Crimes of the Spring Cleaning Monster!l by George Beard and Harold Hutchins. So one time, there was this dude named Welfin Meedley, who hated children skipping school just to go to the beach to relax, so he used his invention to turn him into Melspringmen, a monster that forces kids into cleaning the entire school for spring, ordered by their principal, Mr. Wrupp. Captain Underpants then comes in and see all of the kids getting forced to do the cleaning and says 'Hey, you can't just force kids into doing something they don't like!' but Melspringmen doesn't agree and attacks him. Two students named Beorge Geard and Oarld Uctions do a Flip-O-Rama, which is Melspringmen's biggest weakness. Captain Underpants finds an invention and blasts him with a large ' Whooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooosh' and Melspringmen then turns into back into his human counterpart Mel-I mean Welfin and then the kids along with Captain Underpants make Welfin clean the entire school but making him take one five minute break, okay, the end!"

Melspringmen then shows up at the beach and attacks and hypnotizes them into cleaning the entire school hand by hand with their actual bare hands. George and Harold then sneak past Melspringmen to go to Mr. Krupp to turn him into Captain Underpants, but fails, and starts a 30-minute chase montage. in the past Yesterday’s George and Harold Sulu Crackers and their kids fix the robo suit and to back to the present Melspringmen then loses George and Harold, allowing them to susessfully reach Mr. Krupp, who was still trying to convince the company to give him all of their guacamole, and turn him into Captain Underpants. Melspringmen breaks the roof of Mr. Krupp's office and allows a fight with a Wolf-Chase-O-Rama, because chasing wolfs can be kind of easy, right? Then a green light game it’s Yesterday George and Yesterday Harold and Sulu and Crackers and their kids

After the fight, Captain Underpants gets beaten up badly and then lands into the sewers, which of course, turns him back into Mr. Krupp. But George and Harold have no other choice but to stay in the sewers with Mr. Krupp without Melspringmen looking.

While Melspringmen are forcing the kids, Captain Underpants arrives and uses his long underwear to trap Melspringmen in Melvin's locker room.

Thinking that the nightmare is over, Melspringmen comes out of the room and throws Captain Underpants all the way to Mr. Krupp's house.
