Lylek tube

"There's nothing to fear. Those are lylek tubes. The sound keeps them away. Irritates their brains. My grandfather says its gives them a headache so they don't come around."

- Drua to Emperor Palpatine

Lylek tubes were musical instruments used by the Twi'leks to keep the predatory lyleks away. According to Drua's grandfather, those tubes produced a buzzing sound that steered the lyleks in another direction by giving them a headache.
