10-year-old Timmy Turner is left alone by his parents with a cruel babysitter, Vicky. After being sent to his room early, beaten and miserable from Vicky's treatment, Timmy throws his Magic 9-Ball against the wall in frustration, releasing a pair of wish-granting fairy godparents named Cosmo and Wanda, who help him retaliate against Vicky.
Having been left alone with a demanding, "injured" Vicky babysitting him and using him as a servant, Timmy wishes up a bunch of clones to do his chores for him. However, when they scare Vicky out of her mind and chaos ensues, Timmy must recover them and wish them away.
While Timmy, Cosmo, and Wanda are playing "Greenbeard," Wanda's wand accidentally ends up with Vicky. She uses Wanda's wand as a prop for her fairy costume at her costume party, and Timmy needs to get back the wand since it is granting Vicky's wishes.
Timmy has been invited to Tootie's birthday party, but has to take Cosmo and Wanda along because the former has the fairy flu and he cannot leave them unattended. Unfortunately, Cosmo's constant sneezing wreaks havoc upon Tootie, Vicky, the party guests and Timmy himself. Things appear to be at their worst when Wanda becomes sick and begins sneezing as well, until Timmy and Tootie manage to feed them sauerkraut.
Timmy gets a substitute godparent while Cosmo and Wanda are at boot camp, but the substitute, Jeff, can only make toys; it turns out that Jeff is a runaway elf from the North Pole.
