In Sega Superstars Tennis, Green Hill was fitted with a tennis court.
It was filled with various characters making cameo appearances around the field, mainly Chao, but also seen are Blaze the Cat, Silver the Hedgehog, Knuckles the Echidna and Big the Cat. The net is made of metal with the actual court being set atop one of the hills with waterfalls surrounding it. There are also Rings and Springs spread around the area. This is where many missions in Sonic's world in Superstar Mode take place, including a singles tournament with various Sonic characters.
- The zone looks similar to its appearance in Samba De Amigo Wii, even going as far as to use the same Spring design.
