Standing at 86 feet high, this water coaster propels riders through 950 feet of slides and tunnels at a speed of 42 feet per second, thanks to water-blasting jet-propulsion technology. In addition, for the first time at any Six Flags park, the attraction features new AquaLucent visual effects that create bursts of colors and patterns to intensify the experience.
