However, it was revealed that Rish Loo was serving as a spy to the Confederacy of Independent Systems and was able to control Lyonie with a mystic Gungan necklace in order to force the Gungan Grand Army to turn against Naboo. The plan was a failure when Anakin Skywalker, Padmé Amidala, and Jar Jar Binks discovered that Lyonie was under the influence of the necklace. They then confronting Rish, this led to him stabbing Lyonie, buying him time to escape Otoh Gunga for the surface, where the invasion forces awaited and were to meet with Separatist forces. Attempting to take control of the Gungan Grand Army by spreading misinformation regarding Lyonie's apparent death, Loo failed when Binks, disguised as Lyonie, arrived and deemed Rish Loo to be a traitor. Once more escaping aboard a speeder, he eluded the pursuing Skywalker, while simultaneously leading him into a trap.
