Start a game and go to Hydrocity Act 1. Go to one of the swings that you hang from and grab on. While Sonic is swinging, press Left, Left, Left, Right, Right, Right, Up, Up, Up (the old stage select from Sonic 3). You will hear a confirmation ring noise. Whenever you use a speed booster in this zone you will hear a sound clip of YouTube personality VideoGameDunkey play for the remainder of the level.
