In the spring of 1988, it was announced that the park would indeed get a new coaster. Sarajevo Bobsleds was removed to make room for the new coaster, The Great American Scream Machine, which opened in April 1989. This coaster had multiple loops and for a month was the tallest roller coaster in the world and brought the park back to five roller coasters. The Scream Machine was removed in 2010 to make room for the new Green Lantern stand-up coaster.
