Jambo Was one of the first Zamperla "Joker" rides to be installed in the US, the ride opened in 1998 in the rear of the park near VooDoo. The ride operated for the beginning of the 2006 season, but shut down before summer operation. Shortly after, all rides of the same model in the Six Flags chain shut down, and none have reopened. Jambo was removed in the winter before the 2007 season as well as its sister ride, Trailblazer, at Six Flags Great America.
