The Tri-State Area is the name of the metropolitan area surrounding Danville. The evil Dr. Doofenshmirtz often plans to create chaos in this area, not just the city of Danville itself. For such purposes, he built a scale model of the Tri-State Area.
Some businesses and groups have "Tri-State Area" in their name (e.g. Tri-State Area Public Library, Tri-State Bombers, etc.).
Location Details Edit
In the real world, a tri-state area need not encompass whole states. For example, Chicagoland includes several counties in northeast Illinois along with a few in the most northwest part Indiana and one in the most southeast part of Wisconsin.
In the series, one scale model depicts a geographical area of less than one square mile, ("Toy to the World"). However, another larger scale model was made by Dr. Doofenshmirtz; that scale is unknown. ("That Sinking Feeling").
While describing one of his evil schemes, Doofenshmirtz used a magnifying glass in front of a map of the United States to reveal the Tri-State Area's location. The magnifying glass was positioned near the Denver, Colorado area, which is within driving distance of Mount Rushmore. ("Flop Starz", "Candace Loses Her Head")
The Tri-State Area was founded by John P. Tristate, who united the Bi-State Area with an adjacent, founded by Otto H. Adjacent. Tri-State Area Unification Day is celebrated on July 15. ("Hip Hip Parade")The logo/flag for the Tri-State Area was revealed in Phineas and Ferb The Movie: Across the 2nd Dimension.
The Quad-State Area is where The Regurgitator's base was located in the episode, "Oh, There You Are, Perry". It is mentioned while Major Monogram is briefing Agent P during the beginning of the episode. Other than the fact that The Regurgitator had built his base here, not much is known about the Quad-State Area. Most likely, it is located on the border of Utah, Colorado, New Mexico, and Arizona. So far it has only even been mentioned in the episode "Oh, There You Are, Perry". The name is similar to the Tri-State Area, where Phineas and Ferb live, and the place Doofenshmirtz tries to take over. Judging by the fact that Doofenshmirtz drove there in such a short time, it is most likely close to the Tri-State Area.
Background Information Edit
- Series creator Dan Povenmire has stated that Danville is not in any specific geographical location. The surrounding region changes to fit the needs of the episode's story, leading to Danville and the Tri-State Area being near both Mount Rushmore and the Atlantic ocean at the same time.
- The Tri-State Area may be based on Toy Story's The Tri-County Area.
- In the 2nd Dimension counterpart, it was ruled by Heinz Doofenshmirtz.
- It has more counterparts, one in "Tri-Stone Area", named "Tri-Stone Area", another in "Doof Dynasty" named "Tri-Province Area" and in "Excaliferb" named "Tri-Kingdom Area".
