Brightburg is a city in California that neighbors and rivaled Dimmsdale. As of now, Dimmsdale no longer considers Brightburg a rival city due to it being named worst place to live after the weather Mrs. Turner predicted caused chaos there.
It was a very futuristic, clean looking place that was constantly voted over Dimmsdale as the best place to live. The town was then apparently voted as the worst place to live according to what Chet said in the news due to the weather causing chaos.
The city was unintentionally destroyed by Timmy Turner. After his mother, who had the power to make her weather predictions come true, predicted awful weather for Dimmsdale to destroy it so she could get fired. Timmy, not wanting the town to be destroyed, made wishes to counter it.
He wished for a giant trampoline, which deflected a hail storm of mini-van sized ice chunks in the direction of Brightburg, raining destruction down upon the city. Shortly afterward, Timmy wished Dimmsdale to be encased in a Jell-O mold to protect it from a massive earthquake, causing the shockwaves to further devastate Brightburg. What little of the city that remained fell into a hole caused by the earthquake.
