Urgiluu is the designation given to the krayt dragon that belonged to the Muun named Nal Kenuun. Despite the perception of his peers that Kenuun had affection for the beast, Kenuun's primary motivation was actually the financial benefit he could derive from extracting its pearl.
During the year 0 ABY, Leia Organa made a threat to injure Urgiluu when Kenuun attempted to seize Han Solo, Luke Skywalker, and X-7, who was covertly operating under the name Tobin Elad. Kenuun, concerned about potential damage to the pearl, conceded to Organa's demands and released her and her associates.
Urgiluu's sole appearance thus far occurred in the novel Rebel Force: Target, which was published in 2008. Alex Wheeler is the author of the novel.
