Plot

A kickball finally hits Uranus, reviving the Turbo Toilet, which builds a rocket scooter from the Robo-Plunger. In the original universe, he disrupts one of Melvin's experiments and soon chases that boy until Melvin finds one of Mr. Krupp's clipped-off toenails and extracts it into DNA. He ends up defeating the Turbo Toilet, but soon, people start interrupting his experiments over trivial things and after a year, Melvin finds Sulu's signal in the future and uses the Robo-Squid suit to take George and Harold back home, before he warns them of bad to come.

After turning Captain Underpants back at Mr. Krupp's, the boys try to nap, but miss a full school day and are forced to do five hours of yard work. George then realizes they have a test day tomorrow, but at morning, they fall asleep in their tree house, causing them to get all zeroes. Mr. Krupp gleefully reveals that this was actually "Super Secret Test Day"; while George barely got a passing grade, Harold's grade is failed and, much to the glee of the teachers, separating the two boys in school.

George convinces Harold to travel back with the suit, but they now have duplicates from that point, whom George switches off for them every other day. The next morning at school, they are caught by Miss Anthrope, whom George tries to convince is dreaming, but she sends them to the office, only to realize she has seen two versions of the boys. The Yesterday versions warn the boys to stay from school, but the original boys pull some pranks that make all the school's teachers become similarly crazy. They are soon arrested for various versions, but Mr. Krupp's state gets him sent to an insane asylum.

After two weeks, the Turbo Toilet flies down to Earth, while the four boys convince, with disguises, to break down the asylum wall. Over the intercom, George turns Mr. Krupp into Captain Underpants, who wins the fight, but the Turbo's giant tears of pain fall on his head. Mr. Krupp directs the privy to the treehouse, but where the Turbo Toilet swallows him whole, and Cracker's eggs get cracked on the floor. The Yesterdays discover they are pterodactyl-hamsters, who smash the Toilet while rescuing the Yesterdays. Mr. Krupp is arrested again as an dreaming loon. The four boys regroup, but George points out all the loose ends...
