Phineas and Ferb Tricontinental Area Dancun

According to my research, among the three-state area, Feige and his family live in Danville (Dan Village), Illinois. They have visited Presidential Mountain, which is located in South Dakota, only one state away from Illinois. Fin once tried to use magnets and tinfoil to pull the east coast westward. This state is located in the north-central part of the United States, and its geographical location is suitable. Therefore, one of the three states is Illinois. As for which the other two states are, it remains to be seen. According to research, Illinois is surrounded by three states: Wisconsin, Indiana, and Kentucky.
