Jimmy Neutron: Gotta Blast! Rocket Race (partially found online game; 2002)
Jimmy Neutron: Gotta Blast! Rocket Race was an online Nickelodeon racing webgame released in 2002 that was developed for the 3D Groove game engine. Players would enter codes from Nickelodeon merchandise or Quaker Oats products to build rockets and race them on four maps with Jimmy Neutron characters. Several game sessions would be played over commercial breaks. Not much else is known about the game since it has been defunct for years.
Interestingly, the game's original page remained up on nick.com (albeit no longer with all of its files) until it was finally removed by February 2017.
On July 12, 2017, the game was found on a subdomain of Nick's website, but the only course in the game provided was the space course. The other courses remain lost. It has been speculated that this is a version of the game was meant for after the contest was over, so this version of the game has been dubbed the "Non-Promo Version," while the "Promo Version" still remains lost. You also can’t upgrade your rocket, save any changes made to it, and the ability to look at "flight records" is disabled offline.
