The Dimmsdale 595th Camelot Festival is a medieval-themed fair that is held in Dimmsdale every year.
Held in an open air environment, the fair has several tents with shows inside of them, as well as other actors dressed in medieval style clothing. However, everything is very cheap at this fair. The knight in armor is actually a small man standing on a ladder, the armor he was wearing is fake and easily topples over when Timmy breathes on it. There is also a "magician" who is actually a sales person trying to peddle cleaning products. Inside one of the tents is a "dragon", who is actually a wimpy dog wearing an over sized mask. Timmy is not impressed at all by this fair, although his parents are easily duped into buying stuff at the fair, though it's only because they believe it's the State Fair. Timmy after seeing this wishes himself and his godparents to the medieval times, however they end up taking Timmy's parents along with them, though they didn't notice this yet at that moment.
