Soda Popinski (Russian: Сода Попинский) or Soda Pop as called by Doc made his first appearance in the arcade as the 'Champion of the USSR' in the 1985 game Super Punch-Out!!; although back then he was formally known under the less family-friendly name of Vodka Drunkenski (Russian: Водка Дрункенский). As his name suggests, he is always drinking soda (or in the case of the arcade "Super Punch-Out!!", alcoholic beverages) in between bouts of incessant laughter. The theme music played for Soda Popinski is a quote from The Volga Boatmen's Song, a Russian folk song.
