ride to operate. Triple Play returned for 2007. Also in 2006, Six Flags announced it would replace its sign that sits along Interstate 94 during the off season. The sign, which had been standing since the park opened in 1976, was replaced with a smaller one featuring an LED screen. The new sign went up within a week after the old one was taken down in December 2006, and uses the old sign's post. 2007 marked the introduction of the electronic Flash Pass virtual queue system to Six Flags parks, including Great America. For an additional fee, guests can purchase a Flash Pass and wait in line for a ride without actually standing in line. The system, themed after the DC Comics character, replaced an existing punch card system that was used at the park. As part of the new focus on entertainment, Six Flags introduced a new stunt show, Operation SpyGirl, in the Southwest Territory Amphitheater for the 2007 season. Operation SpyGirl was an original live-action production created by Joel Surnow, co-creator of the Fox television series 24. Operation SpyGirl debuted in May, and closed for the season in August. The show marked several new ventures for Six Flags, including pre-show entertainment in the waiting area, which set up the storyline that the evil archvillain Max Condor had stolen the "Super Viper Rocket" from the agency for which SpyGirl works—as well as a merchandise cart outside selling "SpyGirl" themed merchandise. Operation SpyGirl did not return in 2008. Other new shows introduced for the 2007 season were "Spirit of America" at the reflection pond in front of the Columbia Carousel, and "Show Stoppin'" in the Grand Music Hall. The tented area in front of the American Eagle was converted into Wiggles World in 2007, a third children's area themed after the Wiggles. Wiggles World featured five new rides, Henry's Splash Fountain, the USS Feathersword Play Area, the Yummy Yummy Cafe and the Get Ready to Wiggle Stage show. American Eagle's entrance was relocated to the right of the tent, utilizing part of the entrance building for the adjacent Dare Devil Dive skycoaster, to accommodate the Wiggles area. Great America added The Dark Knight Coaster in 2008, an indoor Mack wild mouse roller coaster themed after the film and located in Orleans Place. The ride is located indoors, mostly in the dark, and has a storyline based around Batman and The
