park opened Road Runner Express, a wild mouse coaster, in 2000, and opened Skycoaster one year later. The Twisted Sisters roller coaster was renamed to Twisted Twins in 2002, upon the threat of a lawsuit from the band Twisted Sister. Kentucky Kingdom opened Greezed Lightin' in the following year, a shuttle loop roller coaster formerly located at Six Flags Over Georgia as Viper and before that as Tidal Wave at Six Flags Great America. It was named after another shuttle loop coaster in the chain at the now defunct Six Flags AstroWorld in Houston, Texas. The Quake was removed in 2004 because of malfunctions and was replaced by the Tornado water attraction in 2005. In 2007, Hurricane Bay was renamed to Six Flags Splashwater Kingdom and Deluge, the first hydromagnetic water coaster, along with Buccaneer Beach, a water play area for young children. Also, the Hellevator drop tower was renamed and rethemed to Superman: Tower of Power just in time for opening day 2007. On June 21, 2007, an accident occurred on the Superman: Tower of Power drop tower which resulted in a 13-year-old girl having both feet amputated at the ankles after a cable fracture occurred on the ride. This accident caused several other drop towers to close down, including Drop Tower: Scream Zone at Cedar Fair parks. On November 29, 2007, it was announced that Superman: Tower of Power would not reopen for the 2008 season. The ride was removed in 2008, the park originally was to replace the ride with a new attraction for the 2008 season, but this never occurred. Instead, Mega Wedgie, a new water slide, was added to Splashwater Kingdom in 2008. Due to major debt by owner Six Flags, the entire northwest section of the park, which included Twisted Twins, Mile High Falls, and the Zeppelin spinning blimp ride, was completely closed for the remainder of Six Flags' operation of the park. On September 21, 2009, Kentucky Kingdom confirmed that Chang was being removed for the addition of Bonzai Beach, a new water park region with a separate theme from the existing Splashwater Kingdom. Bonzai Beach would have opened in the 2011 season to coincide with Six Flags' 50th anniversary that year. Amid a corporate bankruptcy, on February 4, 2010, Six Flags announced the park would cease operations immediately due to the rejection of an amended lease by the Kentucky State Fair Board.
