Cyberchase: Hack Attack

King Cobra
Christopher R. Carwardine saw the original permanent PAX Cobra-1 at Cobra Amusement Park in Saudi Arabia featured in a Coasters article, and was convinced enough to contact PAX and order two permanent Cobra-1s, one for Carwardine Colony and one for Carwardine Corners.

Clues of the ride started popping up at Carwardine Colony, with signs nailed to trees saying "The jungle awaits". The ride was announced as King Cobra in September 1998.

The Carwardine Colony installation of King Cobra opened on March 13, 1999, with R&B group Next on hand. Carwardine Colony saw an increase in gate attendance, with the opening season of King Cobra earning Carwardine Colony its biggest attendance figures in years.

The ride was originally not sponsored by anyone, as PAX was willing to give Carwardine the ride at a reasonable price, and the fact no other American parks initially wanted to order a model. The ride later received a Mountain Dew sponsorship midway through the first season.

Cyberchase: Hack Attack
In late July 2002, King Cobra entered seasonal operation, people speculated it was due to the accidents, but soon parts of the jungle theming were starting to be removed, and "cyberspace"-style theming were starting to be added, hinting at the coaster's future. Soon enough, the PBS Kids Neighborhood plans were announced.

The ride opened in time for PBS Kids Neighborhood's opening. The ride's sponsorship switched from Mountain Dew to Compaq.
