The game's plot differs depending on the version of the game.
Home console version
Once again, Timmy Turner's mother and father have gone on a vacation, and left Timmy with the evil babysitter Vicky. When Timmy tries to make a wish, his fairy godparents Cosmo and Wanda tell him that it's against "Da Rules". Outraged, Timmy wishes he didn't have to follow the rules. As a result, Cosmo destroys the book; when Vicky arrives, she gains possession of Da Rules. She wishes that Timmy was still sleeping, and since she has possession of a fairy item, her wish is granted. Timmy, Cosmo and Wanda go to Fairy Court, and are accused of destroying Da Rules. Jorgen gives the three of them 49½ hours to find the missing pages of Da Rules. Timmy must navigate through ten levels and find the pages before Vicky's wishing goes too far. By the end of the game, everything is back to normal and Da Rules has all of its pages back.
Mr. Crocker gives Timmy a ton of homework to do over the weekend. To make matters worse, Timmy's parents go on vacation for the weekend and leave Vicky in charge, and she orders Timmy to do his homework as well. Additionally, Timmy also needs to get eleven Good Deed stamps so he can get his Good Deed Badge in the Squirrely Scouts. Suddenly, Timmy notices a message in the clouds saying "I wish all these books would disappear," which Cosmo and Wanda grant, causing Da Rules to disappear with them. Juandissimo then reveals himself, saying he tricked Timmy into wishing Da Rules away so that Cosmo and Wanda will get in trouble for it and be banished back to the Fairy Academy. Since Timmy can't wish to have Da Rules returned to them (as it would mean then the Fairy Council would find out about them losing it for sure), he and his fairies have to chase it through the eleven levels, along the way closing the portals, collecting magic dust, and doing the good deeds needed for the badge.
This version notably also features an appearance by Vicky's mother (at Timmy's age, as the level featuring her is set in the past), named Nicky. Here, she looks exactly like 5-year-old Vicky, which is a direct contradiction to the series itself (Vicky's mother resembles her younger daughter, Tootie), although the game was released before Channel Chasers, where Vicky's parents first appeared. Strangely, the dialogue to cutscenes before and during this level suggest that Nicky is supposed to look and act like Tootie. Like her younger daughter's level in the console version, Nicky chases the player throughout her level and will kill the player in one hit upon contact and force a restart of the level.
Game Boy Advance version
Anti-Cosmo and Anti-Wanda plan to make Vicky's evil dreams a reality and to stop Timmy, Cosmo and Wanda from interfering, they steal Da Rules. As they execute their plan, Jorgen then suddenly poofs out and orders them to bring back Da Rules. Until then, they are demoted to third class fairies. Contrary to the description on the back cover (which itself is the same description for the console version), Timmy and his fairies never actually battle Vicky in this version.
Levels (Console Version)
Each level of the game is accessed through a part of Timmy's house and is based on an episode from the television show. Most of them feature Timmy in a different costume. They all begin with an animated loading screen similar to the title cards used in the show complete with the phrase "The Fairly OddParents in..." before the level's title. Besides the house serving as a HUB to the game's levels, Cosmo and Wanda's fishbowl serves as a save point. The game starts with a training level that can only be played once.

Based on the episode "That Old Black Magic". As a result of Vicky having extra classes, Timmy has to go to school on a Saturday. After being splashed by a passing school bus, Vicky wishes Timmy had all of her bad luck for his extra day in school. Suddenly, three Anti-Fairies appear and follow the two to Timmy's school. Denzel Crocker is at the school looking for fairies and Timmy realizes he must capture the Anti-Fairies before they are seen by Crocker and are used to prove the existence of Fairy God Parents.

Timmy has no special costume in this level. This level is accessible through Timmy's front door.
The Ultimate Challenge
Partly based on the episode A Wish Too Far, it serves as the last boss of the game. Returning to Fairy Court, Jorgen informs Timmy, Cosmo and Wanda that they have retrieved all but one single page of Da Rules: the table of contents page, which is all Vicky needs to keep Cosmo and Wanda's wish powers, suspend Cosmo and Wanda's license and have them taken away from Timmy forever. In a desperate attempt to avoid that happening, the judge gets Jorgen to host a show called 'The Ultimate Challenge', where Timmy must battle Vicky, who's under the guise that she is on a TV show and is turned into a dragon, to say, 'I wish I never took the book from Timmy'. After a long, hard battle, Timmy manages to get the wish out of Vicky and Da Rules is returned to Cosmo and Wanda. Timmy has no costume in this level.
