Premier Parks purchased Six Flags from Time Warner and Boston Ventures on April 1, 1998. The following year, the new management team added a dozen flat rides to the park and declared a "war on lines". The Adventure River complex was retired but the flume ride and the Congo Rapids remained. A kiddie water play area also remained as part of a new kiddie ride area called Looney Tunes Seaport. A junior roller coaster called Blackbeard's Lost Treasure Train (now known as Harley Quinn Crazy Train) as well as a kiddie roller coaster called Road Runner Railway were also added, but the star attraction was a floorless steel multiple looping roller coaster called Medusa (now known as Bizarro).
