The Epic Tales of Captain Underpants: Spring-Don't-Clean

The Epic Tales of Captain Underpants: Spring-Don't Clean is an American animated comedy television special made for the Netflix television series The Epic Tales of Captain Underpants, based off of the comic books of the same name written and illustrated by Dav Pilkey.

Synopsis
When Spring comes in the middle of school, George and Harold and their classmates refuse to clean the entire school as requested by Mr. Krupp, they later skip school. Everyone except for Melvin, who uses his "Turn-Myself-Into-A Monster-2,000" to turn himself into Melspringmen, a werewolf monster who plans to hypnotize the students into cleaning the school everyday for 24 hours. So George and Harold must go back to the school with Melspringmen seeing them so they can turn Mr. Krupp into the legendary (but idiotic) Captain Underpants!

Plot
In school, Mr. Krupp officially announces that Spring Break is here, making all of the students (except for Melvin) angry about this. Mr. Krupp then says that people will clean up the  ENTIRE  school in just 24 hours in one day. Not wanting to do it, students George Beard and Harold Hutchins and their classmates go to skip school to go enjoy the beach.

Meanwhile, Mr. Krupp tries to convince a company who makes guacamole to give him all of their guacamole, but it'll cost $1000,000,0000,0000. Melvin, who is outraged of the students behaviors, makes his mother get his invention Turn-Myself-Into-A Monster-2,000 to turn himself into a werewolf to force the kids to go clean the school, in which works as the name of Melspringmen. Because of his stupidity, Mr. Krupp doesn't mind Melspringmen while trying to find a way to convince the company to give him all of the guac. 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, 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 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. 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?

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. When Melspringmen goes to the Jerome Horwitz Elementary School to see if the kids are cleaning, George, Harold, and Mr. Krupp come out of the sewers. George and Harold dry off Mr. Krupp with Dry Spray before turning him into Captain Underpants. 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. George and Harold find Melvin's Turn-Myself-Into-A Monster-2,000 and with the help of Erica (who Melvin didn't hypnotize because she is Melvin's love interest) turn Melspringmen back into his normal counterpart Melvin.
