Most Wanted Wish is the seventeenth episode of Season 3.
Timmy wishes that he was the most wanted kid in the world, resulting in all of Dimmsdale's residents- including Trixie- wanting him. Unfortunately, he's even wanted by the FBI in the sense that he's a criminal! Even worse, now every single fairy in the universe wants to be his godparent, forcing Cosmo and Wanda to go up against every fairy in existence in a Texas cage-match to retain their god-parenthood over Timmy.
During P.E. class, Tad and Chad are picking soccer teammates, and AJ is picked. It's just between Chester and Timmy now, and Tad and Chad end up picking Chester over Timmy. Timmy realizes that they have to pick him now, but instead they choose a rock. Next, in science class, all the kids in fifth grade are paired except for Timmy and Trixie. Unfortunately for Timmy, before he can reach the love of his life, Mr. Crocker pairs up Trixie with a rock. Much to Timmy's dismay, Trixie seems to like the rock way more than she liked him. After being ignored so much and being upstaged by a rock, Timmy wishes to be the most wanted kid in the world.
The next morning, Timmy's parents beg him to let them drive him to school, getting into an argument, but Timmy takes the bus as always, and every kid on the bus wants Timmy to sit with them. At school, Trixie wants Timmy badly, which excites Timmy, but all the girls want Timmy so badly that they chase him home. Timmy goes home covered in kisses, happy with all the attention he has been getting, but things aren't as good as they appear, as always. He becomes so popular that even the FBI wants him, putting him at the top of the FBI's Most Wanted List.
To add onto the mess, all the fairies in Fairy World want him to be their godkid. The only way this can be settled is through a match in Texas: a Texas Cage Match. The way to win the prize is to avoid getting blasted in the butt with a magical boot created by other fairies. Timmy quickly uses an escape pod to get there, and during the match, Timmy uses his wish to distract all the fairies, allowing Wanda to defeat them. Timmy asks why they don't seem to want him, to which Wanda replies by saying that because they are already his fairies, they already have him. This distracts Wanda long enough for Jorgen to blast her hard in her butt. It is down to Jorgen and Cosmo, and Cosmo is an awful shot. Timmy distracts Jorgan as hard as he can, but the wish seems to have a weaker affect on Jorgan, due to his immense power. He is able to coerce Jorgan into granting a few wishes, and begs Cosmo to focus. Cosmo, after repeated failed shots, manages to hit Jorgan in his large butt not once, but four times, giving him the win. The fairies then start fighting over a rock wearing Timmy's pink hat while Timmy and his godparents head back to Timmy's house.
Tired of being wanted, Timmy wishes that he were ignored, something he initially said and did not take seriously. Unfortunately, Cosmo took his words seriously and grants his wish, and Timmy ends up being ignored by everybody, including his fairies.
