Y-O

Y-O, or Why-Oh, was a protocol droid used by the House of Organa, the royal house of the planet Alderaan. It had blue sensors and silver plating. In 9 BBY, the droid served at a royal reception in the Royal Palace of Alderaan, during which Y-O offered Princess Leia Organa a tray of hors d'oeuvres. Organa took one and thanked the droid, who then moved away from Organa's table before the princess's cousin, Niano Organa, mocked her for thanking the droid, which he considered a lower life form.
