The Otoh Gungan Challenge was a sports racing event that was held in the Gungan city of Otoh Gunga on the planet Naboo. It was open to anyone with a single engine sub and was able to achieve a speed of at least 100 longos that was fast enough to outrun any klaa fish. Amongst the rules included no weapons being allowed which meant that military subs were prohibited unless they were decommissioned. These were the only restrictions for anyone entering into the competition otherwise the rules were wide open for contestants.
