The Soggy Salvation of the Swirling Sweatnami

The Soggy Salvation of the Swirling Sweatnami is the eleventh episode of The Epic Tales of Captain Underpants.

Synopsis
The boys travel back in time to stop Mr. Krupp from becoming a bully by stopping his mother, Bernice Krupp, from making the key moment that started it all happen. They succeed in making Young Krupp's talent show a success, only to find that their plan has boosted his proficiency and the wealth he has earned turned him into a ruthless successful child-laboring businessman. When Melvin overthrows the new chain of command and Captain Underpants is left powerless, will George and Harold be able to return everything back to normal?

Summary
George Beard and Harold Hutchins were thinking to make Benjamin Krupp a nice guy, but Erica Wang and her assistant Dante came by and Erica told them that most of the bullies' awful life make them bullies, so George and Harold went to Krupp's house, where they meet his mom, Bernice Krupp. She told them that at a fourth grade talent show, he became a mean guy ever since he was booed by everyone. When they heard that, the boys run to Melvin Sneedly's house for his Time Toad 2000 to make Krupp a nice guy. After seeing everyone throwing fruits at him and went five minutes to undo that over, and this time, it worked. After they went back to the present time, they see a building cell, named Krupp Corp. They were taken in by evil robots, where they found Krupp, who was a meaner business man than a mean principal. Alternate timeline Erica Wang told them that Mr. Krupp turned the school to toy factory in this timeline.

George and Harold make a comic to tell her to help them, but Alternate timeline Melvin Sneedly told them he worked for Alternate timeline Benjamin Krupp, who makes him his furniture, so he told them that he'll make them a 3-D Hypno-Ring and he'll be free. George and Harold hypnotizes him and turns him into Captain Underpants. Melvin’s robots attack him and toss him into toxic waste that give him super powers, and George and Harold escape with a sweatnami with the kids, so Melvin used his Factory-Tron 2000 to kill them, but Captain Stretchypants came to stop him, in which he successfully does. After this was dealt with, the boys fixed the timeline back to normal and Erica tell them that Krupp was born mean, which was a fact.
