## Plot
### Introduction

Fourth-graders George Beard and Harold Hutchins skate over ketchup packets in the school gym until their mean-spirited principal, Mr. Krupp, catches them and makes them write a 100-page essay on good citizenship. The boys instead create a comic book about a superhero called "Super Diaper Baby", to Mr. Krupp's surprise.

### Plot

Expectant couple Bill and Mary Hoskins rush to the hospital; meanwhile, Deputy Dangerous and his talking pet dog, Danger Dog, drain Captain Underpants of his superpowers. They convert the superpowers into juice, intending to share it to give themselves powers. Danger Dog drinks half of the juice, but the police come to arrest them before the Deputy gets a chance to drink. They run away from the police, ending up below the hospital.
At the hospital, Mary gives birth to a boy named Billy. The attending doctor gives Billy a "spank of life", accidentally sending him out of the window. He lands in Deputy Dangerous' container of juice and drinks it, gaining superpowers and becoming Super Diaper Baby. Billy then overpowers Deputy Dangerous and Danger Dog, who are arrested.
Danger Dog and Deputy Dangerous break out of jail and escape to their secret lab, where the Deputy invents a crib device that would transmit Billy's powers to him at midnight. They deliver it to the Hoskins under pseudonyms, "Deputy Un-Dangerous" and "Safety Dog". Billy poops before midnight, and Mary takes him out of the crib as the device turns on. It transmits the poop, turning Deputy Dangerous into a small piece of feces. The next morning, Deputy Dangerous invents a robotic ant mecha-suit and intends to use it to destroy the city as an act of revenge. Danger Dog does not take the Deputy's efforts seriously, calling him "Deputy Doo-Doo" and choosing to cause mischief instead of destruction.
Billy's father sees the ant suit, scaring him, and Billy leaves his home to defeat it. Billy fights the Deputy, who captures him and throws him into a nearby nuclear power cooling tower. Danger Dog flies into the tower, saving Billy. Deputy Danger falls into the tower and the radiation makes him grow larger. Meanwhile, Billy's family adopts Danger Dog and renames him to Diaper Dog.
Deputy Dangerous continues his destruction of the city and Billy and Diaper Dog seek to stop him. They trick him into attacking himself and wrap him up in a giant roll of toilet paper before flying him to Uranus. Billy and Diaper Dog order superpower juice at a restaurant on Uranus and give it to Captain Underpants, restoring his powers.

Upon reading it, George and Harold are inspired create something without poop and decide to make their sequel about pee. Offended by their new book, Krupp send them to detention.

### Plot

The Hoskins and Diaper Dog set up a picnic in the park where Billy ends up over a tree, but he and Diaper Dog force a doll back from a bully, get a ball out of a portable toilet, and get a toe-broken kid to the hospital in a few seconds. That night, Mr. Hoskins feels depressed, but after a reminder by his wife, he decides to read Mechafrog and Robotoad are Enemies to Billy. Billy can now read it to him, instead, due to the powers he gained. Meanwhile, two criminals called Dr. Dilbert Dinkle and Petey the Cat sneak into Jim's Bank, but before Dr. Dinkle can measure for his invention, Petey accidentally pushes a lever, and Dr. Dinkle turns into water. Petey accidentally destroys the invention, leaving Dr. Dinkle made out of water permanently. Dr. Dinkle likes being made out of water when he is able to turn into a puddle, sneak into the vault, and steal the money. Back at his home, Dr. Dinkle finds out he will never pay the water bill and his supply is cut off after two weeks. Petey complains he needs water for drinking, but Dr. Dinkle goes to sleep. Petey drinks him in revenge. The next morning, Dr. Dinkle yells to be let out, right when Petey needs to urinate and the cat leaps into his litter box. Dr. Dinkle discovers that he is now made out of urine, and Petey coins the name "Rip Van Tinkle", much to Dinkle's dismay. Petey makes jokes at his expense and makes him go to multiple places, all of which kick him out for his smell.
The following night, Rip Van Tinkle puts Petey in the Robo Kitty 3000, before he evaporates and rains pee on people. Soon, the pee drops break into houses to steal toilets for the Robo Kitty 3000 to destroy. One drop gets caught by Billy, so it tricks him into thinking that it will repair the toilet, gives him a juice box in bed, then the Kitty destroys the toilet. The next day, Mr. and Mrs. Hoskins are in pain, and they put on diapers, while the mayor decides to drain the pool. The pee drops unite to recreate Rip Van Tinkle, while Petey steals diapers to sell to the people who were robbed of toilets. Rip Van Tinkle takes Petey's money, and the cat soaks him up with toilet paper. Super Diaper Baby and Diaper Dog arrive, only for Petey to evolve the Robo Kitty 3000 into the Supa-Mecha Kitty 3000. Super Diaper Baby flies to buy catnip and pour it inside the control seat. Petey goes crazy after smelling the catnip, bounces around, and detaches the Supa-Mecha Kitty 3000's head. Super Diaper Baby and Diaper Dog grab Petey and carry him to jail.
A drop of pee gets flicked up and lands in the Mayor's pool, where it grows into an enlarged Rip Van Tinkle, whom the duo finds wreaking havoc at the train tracks. Rip Van Tinkle uses the train as nunchucks and hits both of them. Rip Van Tinkle overpowers the two and smashes a building on top of them. Super Diaper Baby remembers that a week before, he put his juice box in the freezer and it froze solid, giving Diaper Dog the idea to push down on the Earth. It works and makes the Earth move farther from the Sun. Rip Van Tinkle freezes, and Diaper Dog and Super Diaper Baby carry Rip Van Tinkle, while Super Diaper Baby gets an idea of how to cheer up his father.
Back at the Hoskins' house, Billy tells Mr. Hoskins that there was an ice monster outside and that he was brave enough to stand up to it. Diaper Dog, hiding behind and making a voice for Rip Van Tinkle, talks to Mr. Hoskins. The "ice monster" is "scared" of Mr. Hoskins' talking and leaves Earth. While someone asks for Mr. Hoskins' autograph, Super Diaper Baby and Diaper Dog take Rip Van Tinkle to Uranus, only for Deputy Doo-Doo to say "The Baby again." They return to Earth, and take a picture with Mr. and Mrs. Hoskins with a news reporter and put out a newspaper saying, "Diaper Clad Dad Saves The Earth!".
