Yerba is the island country the Victorious gang visits in the episode Locked Up! The country is ruled by a chancellor, who remains unnamed throughout the episode..
At the time of the filming of the episode, Yerba was at war with rebel forces. This is the reason why soldiers are seen frequently throughout the episode. The primary national language is an unknown native language(none of their words can be traced to existing launguages), mixed occasionally with English words. The landscape of Yerba is bleak and desolate, and the urban areas are poor and underdeveloped. Despite the fact that the Victorious gang stayed at the best hotel in the country, the hotel was disgusting and even the prison is unsatisfactory.
