covered the looping coaster in Texas Monthly that year, noting the ride only lasts 28 seconds, adding the second half of the ride is carried out in reverse: "If there is anything more frightening than entering a 360-degree loop in a coaster car, it is entering a 360-degree loop backwards in a coaster car". Thunder River, installed in 1980, has been described as the "first commercially successful river-rapids ride". Warp 10 took over the former site of the Astrowheel in 1981; it was later moved to Plaza de Fiesta in 1987 and renamed Warp 2000. Warp 2000 was operating as Crazy Legs at Six Flags Over Texas in Arlington, as of 2016. The ten-story Sky Screamer debuted in 1983. Louis B. Parks of the Houston Chronicle said of the ride at the time: "After being shot to the top of the tower in a super fast elevator ride, you are now about to free fall back to the bottom. As you reach the base of the tower, several weeks ahead of your stomach, you will be swooshed along a curving track, changing your horizon and your bearings, and braked to a quick stop while lying on your back." In 2013, the newspaper's J. R. Gonzalez recalled, this "crash course in physics ... wasn't as scary as the Texas Cyclone, nor as drenching as Thunder River, but it did make for a quick thrill". AstroWorld removed the ride during the 1990s. XLR-8 was installed in 1984. Looping Starship was installed in 1986. Arrow-Huss originally manufactured Tidal Wave as "Shoot the Chute" for the 1984 World's Fair in New Orleans. Six Flags purchased the ride after the fair's bankruptcy and installed it at AstroWorld in 1988, replacing the Lost World riverboat ride. It was described as "a flume designed to plunge passengers down a series of slides in a small boat" and "dependent upon a stream of pumped water". Ultra Twister was installed in 1990. The ride stood nine stories tall and had a vertical drop followed by a series of barrel rolls. Mayan Mindbender was installed originally as Nightmare at Boblo Island in 1995, becoming the park's first indoor roller coaster. The coaster was housed inside a Mayan pyramid. The ride's trains had twelve cars made by the Dutch company Vekoma, with T-bars used as restraints. In 2004, Josh Harkinson of the Houston Press wrote, "the coaster resembles Indiana Jones skiing
