Plot:
After Mr. Krupp reads the first "Super Diaper Baby" comic, he is furious and yells at the boys for creating such a rude and offensive comic, suggesting that they try and write about something more appropriate. He gives them the book How the Grinch Stole Christmas! as an example and states that it was his favorite book during his childhood (with the last seven pages torn out). The book inspires the boys and they decide to make a sequel, about pee,which only angers Mr. Krupp even more.

The Hoskins and Diaper Dog set up a picnic in the park where Billy ends up over a tree, but then 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 "Mecha-frog and Robo-toad are Enemies" to Billy, but he 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, careless Petey accidentally pushes the lever and Dr. Dinkle turns into water, then Petey accidentally destroys the invention, meaning that Dr. Dinkle is made out of water permanently, but Dr. Dinkle thinks that he actually likes being made out of water when he is able to turn into a puddle and sneak into the vault to get the money. Back at his home, Dr. Dinkle finds out he will never pay the water bill, but his supply is cut off after two weeks. Petey complains he needs water for drinking, but Dr. Dinkle goes to sleep and Petey drinks him in revenge. The next morning, Dr. Dinkle yells in surprise 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 as Petey coins the name "Rip Van Tinkle" and after Rip Van Tinkle's dismay, the cat points jokes to him, making him go to multiple places, all of which kick him out for reeking.

The following night, Rip Van Tinkle puts Petey in the Robo Kitty 3000, before he evaporates and rains pee on people. One drop tricks Billy that he 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, but put on diapers, while the mayor decides to drain the pool. The pee drops unite to create Rip Van Tinkle, while Petey steals diapers to sell to the people who were robbed of toilets, but Rip Van Tinkle takes Petey's money and the cat soaks him up with toilet paper. Diaper Baby and Diaper Dog arrive, only for Petey to evolve the Robo Kitty into the Supa-Mecha Kitty 3000. Diaper Baby flies to buy catnip and pour it inside the control seat. Petey goes crazy after having the slightest sniff of the catnip, bounces around, and detaches the Supa - Mecha Kitty 3000's head. Super Diaper Baby and Diaper Dog grab Petey and carry him off 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 right on top of them. However, 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, making the Earth go farther and 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 (Rip Van Tinkle) and tells his dad he's brave enough to stand up to him. 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 come back, and take a picture with Mr. and Mrs. Hoskins with a news reporter and put on a newspaper saying "Diaper Clad Dad Saves The Earth!".
