Mom and Dad have finally realize the fact that Timmy has fairy godparents! When Timmy's parents discover Cosmo, Wanda, and Poof, Timmy must keep Jorgen from finding out about it; otherwise, he will lose his fairies forever.
Timmy wishes for the "Timmy Land" amusement park in his backyard. At the rollercoaster, Wanda tells Timmy that his wish may be risky because he wished for the amusement park in his backyard when his parents are home. Cosmo says that Timmy's parents are too clueless to know.
That's when Timmy's dad showed up and starts suspecting something weird is going on. He tells Mrs. Turner and they then start spying on Timmy.
At first, they think Timmy is a witch, Italian, or a time traveler. In his room, Timmy wished for a big race track. Wanda still thinks his wish may be too careless. Of course, Timmy answers that there's nothing to be afraid of... then his parents barge in to his room. Left with no choices, Timmy has to tell his parents everything and introduces them to his fairies, knowing this is breaking one of the biggest rules in Da Rules. Mom has a better idea to not tell Jorgen about this,
When Jorgen appears, Cosmo and Wanda hide his parents while Timmy distracts him, telling him to go to the amusement park with Poof. Jorgen does so and when he's gone, Timmy poofs his family back to his room. Mom tells them that she must do her chores and Dad tells them that he will continue terrorizing Dinkleberg, but Timmy says that Cosmo and Wanda can do it for them.
Jorgen's voice is heard again and Timmy wishes to hide his parents again. Jorgen then says that something suspicious is going on. To throw him off the track, Timmy tries to distract him by saying he should try the "Turner of Terror" because it's really cool. Jorgen agrees, then Timmy poofs his parents back to his room again. Mom and Dad appear with terrorized faces, because Cosmo
made them tiny and a squirrel almost attacked them.
Dad told Timmy that his all life was Passed before his eyes and he said that it was boring. But Timmy says that their life will be not boring again because his parents can wish for anything. Mom wished for "The Mom Show with Mom" and Dad wishes to become President of the United States. Timmy then asks Mom anything else what she want to wish for, Mom says that she wants to see the world. First they went to explore the Eiffel Tower, then Japan, Antarctica, the Egyptian Pyramids, Hollywood, Easter Island, Africa, The Moon, Tower of Pisa, Taj Mahal, London, The Statue of Liberty, the Titanic, and Mexico.
At home, Mom says that it was the greatest day of her life, but Dad says that he has only one wish left. He wishes to find his wife's wedding ring, which he lost and replaced with a meatball. The ring appears and Mom is happy; they say thanks to the fairies.
But trouble comes when the rollercoaster crashes into Timmy's room, Jorgen and Poof aboard. Jorgen declares that he has caught Timmy red-handed, saying a talking golf ball told him about it. Cosmo, Wanda, Poof, Timmy, and Dad all cry because it seems like Timmy's going to lose his fairies. But then Mom realizes how much his fairies mean to him. So Dad begs that he and his wife's memories be erased so Timmy can keep his fairies. Jorgen agrees, erasing their memories, unwishing everything that Mom and Dad wished for, and setting time back. Everything is back to normal, but Timmy does wish for his dad to find the wedding ring that was unwished. In the end, Mom and Dad are seen riding the Turner of Terror with Timmy, Cosmo, Wanda, and Poof (in goldfish form).
Even though Timmy broke one of the biggest rules in Da Rules, Jorgen still lets Timmy keep his fairies, because he is touched by the moment and he is also in a good mood after riding the "Turner of Terror".
