Just before Sonic transforms into Super Sonic near the end of the game, the surviving crowd in Station Square can be heard in the background chanting Sonic's name to encourage him. This crowd recording is actually comprised of over one thousand attendants in the audience for the official reveal of the game at the Tokyo International Forum on August 22, 1998. The chant was led by special guest Hiroshi Fujioka portraying Segata Sanshiro, the Japanese advertising mascot for the Sega Dreamcast's predecessor the Sega Saturn, and recorded by Sega to use in the game.
