The Superduper Mega Superstore is a mall-like structure that is the largest supplier of everything in the Tri-State Area in "Vanessassary Roughness" that Phineas, Ferb, Candace, Stacy, Perry, Linda, Vanessa and Dr. Doofenshmirtz all visited on the same day. Phineas said it has "52,637,000 sq. acres of unbridled consumerism all under one roof. In "Ain't No Kiddie Ride " it shows that they have kiddie rides in front of the store. This mall must be a little bit old because Phineas said that he used to come here and ride the kiddie rides when he was little.
