In 1985, Children's World was rethemed as Bugs Bunny World, as Magic Mountain had abandoned the Trolls in favor of Warner Bros.' "Looney Tunes"/"Merrie Melodies" characters. That year, Michael Jackson visited the park, riding rides such as Colossus, Revolution and Roaring Rapids. In 1986, the park added a steel stand-up looping roller coaster called Shockwave also designed by Intamin. This coaster was located in the back of the park replacing Sarajevo Bobsleds. At the end of 1988, the coaster was removed as part of a ride rotation program and went to Six Flags Great Adventure in 1990. It was removed from there in 1992 and was repainted white and rethemed upon its removal to Six Flags Astroworld. There it was known as Batman The Escape. When Astroworld closed in 2005, the ride was put in storage at Darien Lake.
