Note: Captain Underpants and Frozen not owned and created by me. This story takes place after the Captain Underpants animated film. This story is for Fanfiction and Fanpop. Things at Mr. Krupp's school were actually going pretty good. Mr. Krupp often got mad at the antics of George Beard and Harold Hutchins, but the 3 of them became semi friendly rivals instead of being straight up enemies.

George Beard said "Things sure better now."

Harold Hutchins nervously said "Do you think that things will get worse?"

George said "No way."

Harold said "I just hope that Professor Poopypants doesn't plan on coming back."

Meanwhile Professor Poopypants was planning on coming back. He was in his new lair and was working on a new invention. He said "Those 2 bratty kids and their oddly dressed captain defeated me last time, but I plan on changing things up this time. Last time I made the mistake of having my shrink ray and my enlarge ray together, but this time I will only bring my shrink ray. That way I will shrink the 2 brats and the captain and trap them. Ha, ha!"

The next morning Mr. Krupp was interviewing Princess Anna who wanted to be the new science teacher so she could meet Captain Underpants. Mr. Krupp read her resume and said "It doesn't seem like you don't have any experience teaching science."

Princess Anna said "That's true."

Mr. Krupp said "Have you ever taught any type of class?"

Anna thought about it and said "I was once a substitute math teacher."

Mr. Krupp said "Good enough. You are the new science teacher."

Anna smiled and said "Thank you Mr. Krupp. I have wanted to work at this school ever since I heard about Captain Underpants. He seems like such a cool hero. He inspired me and my sister to be like him."

Mr. Krupp angrily said "Captain Underpants isn't real."

Anna said "Where is the science room?"

Mr. Krupp said "I don't know."

Meanwhile Professor Poopypants returned to the school. He used a megaphone and said "Come out comic book kids and Captain Weirdo."

Mr. Krupp angrily said "What is going on?"

Harold nervously said "I think that Professor Poopypants is back."

George said "I'm sure that it's somebody else."

Professor Poopypants said "I am Professor Poopypants."

George said "Oh no." George and Harold found Mr. Krupp and snapped their fingers. Mr. Krupp changed into Captain Underpants.

Captain Underpants heroically said "Tra la la."

George said "The evil professor is back."

Captain Underpants proudly said "Don't worry sidekicks. I will stop him." Captain Underpants ran outside and said "I will stop you."

Anna saw Captain Underpants and said "How cool."

Professor Poopypants said "Oh really?" Captain Underpants said "Oh yes." Professor Poopypants said "Are you sure about that?" Captain Underpants thought about it and said "I am 90% sure - 10% + 15% - 25% + 30%." Professor Poopypants said "You could of just said 100%." Captain Underpants thought about it and said "Oh. You're right." Professor Poopypants got out the shrink ray and said "I have no more time for your foolishness." The professor shrunk the captain. The professor smiled and said "This is my biggest victory!"

George said "Technically this is your smallest victory." Harold laughed.

Professor Poopypants angrily said "No more jokes!" The professor shrunk George and Harold.

Anna said "Oh my. The captain is the size of a atom. He needs help. He needs another super hero. Luckily I am a super hero. Kind of."

Professor Poopypants said "Now that I have shrunk my 3 arch enemies I might as well shrink the rest of the school to prove to the world the dangers of making fun of mildly silly names."

George and Harold were scared. George said "I don't know what to do." Harold said "Neither do I."

Captain Underpants confidently said "I'm not scared. Everything will work out."

George said "Do you have a plan?"

Captain Underpants said "Plans are overrated."

Professor Poopypants tried to shrink the school, but the shrink ray wasn't working. The professor said "I'm afraid that my shrink ray had enough juice left for only 3 people. I'll be okay as long as I don't suddenly get a new enemy." Suddenly the professor got a new enemy.

Anna showed up dressed as a super hero. Her costume was inspired by Captain Underpants so she was shirtless and pantless. Anna was only wearing her pink bra, underwear, and a curtain that she used as a cape. She said "You should release the captain. If you don't you'll have to fight Super Chocolate Lover." Anna tried to look heroic and tough, but the professor thought that she looked ridiculous.

Professor Poopypants said "Heroes these days have terrible fashion."

Captain Underpants said "Actually I am very fashionable."

Anna said "Since your ray is out of shrinking juice you are out of ways to defeat me."

Professor Poopypants said "That may be true, but I still have the captain shrunk and you can't stop me."

Anna looked around and said "Where is the enlarging ray?"

Professor Poopypants said "I'm smart enough to not bring the enlarging ray with me. The only way to enlarge the captain and the kids is to break the shrink ray. I shouldn't of told you that."

Anna reached for the shrink ray and said "Hand it over Peepants."

Professor Poopypants said "My name is Poopy, not Pee."

Anna said "Either way you need to change your pants." The captain and the kids laughed. Anna tried to grab the shrink ray, but the professor kicked her. Anna said "It will take more than a little kick to stop me."

Professor Poopypants smiled and said "Luckily I had karate classes recently." George said "Why?"
Professor Poopypants said "Plot convenience."
The professor kicked Anna who crash landed into the school. Anna passed out.

Captain Underpants said "That's not good."

George said "We know that Captain Obvious."

Captain Underpants said "Actually my name is Captain Underpants. No offense, but you should know that by now."

Professor Poopypants said "I can't be stopped now."

Captain Underpants said "Unless another hero in their underwear shows up."

Professor Poopypants angrily said "That better not happen." That's what happened.

Queen Elsa showed dressed as a super hero. Elsa was also only wearing her bra, underwear, and a curtain cape, but Elsa's is light blue instead of pink. Elsa tried to use her cape to cover herself up and whispered "Anna will pay for pressuring me to dress like this."

Professor Poopypants had a villainous smile on his face. He said "I don't see any reason to be worried. I'll defeat her with my karate skills."

Elsa said "No you won't." Elsa froze Professor Poopypants. Elsa broke the shrink ray which made the captain and the kids return to their regular height.

Anna got up and said "What happened?"

Elsa said "Don't worry Super Chocolate Lover. I took care of the professor."

Anna said "Thank you Super Icicles."

George said "If this girl has ice powers why didn't she show up first?"

Anna said "Plot convenience."

Harold said "So you dress like Captain Underpants too?"

Anna proudly said "We sure do."

Captain Underpants said "Well now that the villain is gone. Lets party."

Anna said "Alright. I'll bring the chocolate."

Elsa said "And I'll have plenty of ice."

Professor Poopypants said "Is anybody going to unfreeze me?"
