First Disney bought us the “Phineas & Ferb” character meet and greets at Disney’s Hollywood Studios. Then we had Agent P’s World Showcase Adventure opened at Epcot. It looks now the pair will also be at Downtown Disney in a new adventure called “Phineas and Ferb & YOU: A Brand New Reality.” The experience, which will take place next to Bongos Cuban Café and will allow guests to step onto a platform and virtually interact with Phineas, Ferb, Dr. Doof and Agent P (in their animated forms) on a screen above. Fans can expect to experience any one of 20 different interactions, from dancing “The Platypus Walk” to getting caught in Dr. Doof’s Freeze-inator. Afterward, guests can digitally share a complimentary souvenir photo of their animated interaction with their family and friends. Special “Phineas & Ferb” merchandise will also be available. “Phineas and Ferb & YOU: A Brand New Reality” will run through December 1, and is open from 2-9:30 p.m., daily.
