Granting the wish, the Pixies gain control of both Earth and Fairy World which are built in the image of Flappy and the Pixies respectively. Cosmo and Wanda are put in Fairy Jail by Jorgen, but escape by distracting him with a song of their enduring love for each other ("Floating With You"). With Pixie magic flooding Fairy World, Cosmo sends Wanda down the rainbow bridge connecting Fairy World to Earth before it is dissolved. Now that the Pixies have taken over Fairy World, and Flappy Bob has made the world safe, the only people who are having fun are adults and the Pixies ("Unfundamentals"). Flappy soon starts questioning if what he is doing is what he really wants. Later, Flappy overhears H.P. and Sanderson gloating on how they had manipulated Flappy in order to rule Fairy World. Flappy realizes that Timmy was right about the Pixies all along. He decides to embrace his clown heritage and get everything back to normal. Timmy tries to get everything back to normal but with the Pixies in control of magic, there is no way to break the contract. Timmy and Wanda are afraid all is lost, but Flappy Bob appears in his clown costume and states there is still hope. The Pixies raised him to be a boring businessman, but because of that he was able to find a loophole in the contract. Timmy and Flappy recruit the kids in making the Earth as fun as possible while preventing the adults and Pixie Guards that are trying to stop them ("The Reprise Remix"). The Pixies soon get word from this and go down to Earth. H.P. and Sanderson admit using Flappy for other motives, but the latter reminds Flappy they still have the contract Flappy signed. Flappy admits that everything in the contract is binding, however it states the world will reflect fun "as defined by Flappy Bob". Flappy then states his new definition of fun is everything the way it's supposed to be which means the Pixies are forced to declare defeat. H.P. rips up the contract and uses his phone to turn everything on Earth and Fairy World back to normal. Wanda brings Flappy his parents who have been searching for him for 37 years (which Wanda was able to do due to a loophole) and reunites with Cosmo. Everything seems normal until both Happy Peppy Gary and Betty open a new Learnatorium. Cosmo & Wanda use their magic to turn everything at the Learnatorium fun and puts on a concert ("Kids Just Being Kids Reprise").
