This planned community is where most people in Dimmsdale moved to after Mrs. Turner sold their houses. All of the citizens drink Dimmadome Farms Milk, except for Timmy, which has some ingredient that causes the drinker to enter a trance-like state, and they try to get other citizens to drink it as well. After Timmy threw his Fizzy Juice into the supply of milk, everyone was free from their trance, Dimmadome Acres was turned back into a garden field, and Doug Dimmadome forgot all about Dimmadome Acres. Mrs. Turner then sells everyone back their houses since this place was no longer Dimmadome Acres and nobody had anywhere to live at the moment.
All of the houses and yards are exactly the same, but are much bigger and nicer than the normal homes in Dimmsdale. It has a tennis court, a swimming pool, and a golf course. The community is surrounded by an iron gate, inside which also has bushes with sharp spikes that appear as an extra security measure to prevent escape.
After Timmy Turner made a wish for his mother to be better at her job selling houses, she had become so good that she sold everyone's home in Dimmsdale including their own house. With the money they earned from selling their homes, the Turners moved to the Dimmadome Acres, a planned gated community owned by Doug Dimmadome. Everyone drank a special brand of milk, and acted exactly the same, eventually resembling mindless zombies that convince people to drink the special milk. Timmy was unaffected because he was drinking fizzy drinks to practice for a belching contest, but his friends, family, and even his fairy godparents began to aggressively persuade him to drink the milk. Timmy was easily able to flee them, since everyone in the community rode on extremely slow moving Segway-like scooters.
Timmy soon wandered into the tennis court, which flipped over and dropped him into a milk factory, where his family, Vicky, A.J. Chester and his dad, Mr. Crocker, as well as Cosmo and Wanda in cow form, being milked along with other cows to fill a huge tank of milk. Timmy is cornered by them and Doug Dimmadome, who reveals that he is using the milk to make the citizens of Dimmsdale his slaves. Timmy uses his fizzy juice, which had magic properties thanks to his fairies, and tosses it into the tank of milk, causing it to explode and magic liquid to flood the entirety of Dimmadome Acres, turning it back into a garden, freeing everyone from their trance, and erasing Doug Dimmadome's memories of Diammadome acres. A deer driving a bulldozer than pushes Doug Dimmadome away. All the other citizens besides Timmy are left with their minds wiped as well, and return to their normal homes in Dimmsdale when Mrs. Turner sells them back to everyone.
