Sega Splash! Golf stars two anime-styled humans named Rush (male) and Miel (female) who set out to become professional golfers. Sonic the Hedgehog is given the "with" credit in this game as he is present throughout the game as a personal coach and caddie. Other optional caddies are available such as Tails, Ulala, the Puyos, NiGHTS and others from SEGA franchises.
