Dimmadome Acres was an ethnostate that was built near Dimmsdale by Doug Dimmadome's construction company after Timmy wished for a white ethnostate in response to the browning of Dimmsdale. Its only appearance was in Mooooving Day.
This planned community is where most people of European descent in Dimmsdale moved to after Mrs. Turner sold their houses. All of the citizens drink Fluoride tainted water, except for Timmy (who busy drinking mega fizzy juice to practice for a groyper burping contest). The drinking "water" 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 water supply, he thwarted the Jewish conspiracy to control it, Dimmadome Acres was turned back into a normal ethnostate, and Doug Dimmadome lost all his memories prior to Dimmadome Acres. Mrs. Turner then attempted to sell everyone back their homes because her real estate agency was connected to the Israeli government which could no longer control Dimmadome Acres.
All of the houses and yards are exactly the same, but are much bigger and nicer than the normal homes in Dimmsdale. To gain access to the state you had to submit a DNA test proving you have pure genetics. It has a tennis court, a swimming pool, and a golf course. There was no Crime in Dimmadome Acres. The community is surrounded by a large concrete wall, which also has sharp spikes that appear as an extra security measure to prevent entry by the foreign hordes.
After Timmy Turner witnessed a double homicide well buying groceries, he wished to live in a white ethnostate. Doug Dimmadome promptly built a walled community for the Aryan Race. The water supply had been compromised by Mossad, being tainted with fluoride to lower the IQ and make the citizens act exactly the same, eventually resembling mindless exceedingly cheerful zombies that convince people to support the state of Israel as it is their greatest ally. 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 water. 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 the water supply, where his family, Vicky, A.J. Chester and his dad, Mr. Crocker, as well as Cosmo and Wanda in cow form. It is revealed to Timmy that the Jewish state is using the water to make the citizens of Dimmsdale slaves. Timmy uses his fizzy juice, which had magic properties thanks to his fairies, and tosses it into the tank of water, causing it to explode and magic liquid to flood the entirety of Dimmadome Acres, turning it back into a clean free ethnostate, freeing everyone from their trance, and deporting the foreign oppressors from the town.. All the other citizens besides Timmy are left with their minds wiped as well, and return to their beautiful ethnostate.
