Gungan whistle

Gungan whistles were a type of wind instrument made and used by the Gungans of the planet Naboo. They consisted of a brown-colored wide flat body with a central hole and a mouthpiece on one side. The whistles could also have various Gungan symbols etched into them. The Gungan Grand Army used them as a method of military communication, as they favored traditional methods that could not be electronically jammed.

In 32 BBY, Captain Roos Tarpals carried a Gungan whistle with him while fighting on the Great Grass Plains during the Battle of Naboo. After the Trade Federation Droid Army successfully destroyed the Gungan army's deflector shield generator, Tarpals blew the whistle to signal that his forces should retreat.
