Ko'okiri Body Plunge: A near-vertical (70-degree drop) speed slide with a trap-door start that passes through the Krakatau volcano, falling 125 feet (38 m). The slide will also pass through one of the pool attractions at the base of the volcano, described by the park as a world's-first feature.

The fastest slide at Universal’s Volcano Bay in Orlando is the Ko’okiri Body Plunge. This high-thrill attraction features a "trap-door" release that sends riders on a near-vertical, 70-degree drop for 125 feet. During the descent, riders can reach speeds of up to 40–50 mph as they plummet through the center of the Krakatau volcano. Because it is a "body slide" where the rider’s skin is in direct contact with the water, the sensation of speed is much more intense than on the park’s raft-based coasters. In 2026, Ko’okiri remains the most popular thrill at the park, often requiring guests to utilize the TapuTapu wearable to join a virtual queue. For those seeking speed without the vertical drop, the Krakatau Aqua Coaster offers a fast-paced magnetic-launch experience, but for raw velocity and adrenaline, the Ko’okiri Body Plunge holds the undisputed title.
