Sonic in the Jade Gully Zone.

Jade Gully Zone is a scrapped level that would have appeared on the Sega Saturn cancelled video game, Sonic X-treme. This is the first zone of Sonic X-treme. The stage is shown to be a peaceful area, nearby a gully, hence its name. It has similar designs as to Green Hill Zone, Emerald Hill Zone from Sonic the Hedgehog 2, and Mushroom Hill Zone from Sonic & Knuckles. Fang the Sniper and a boss called "Emerald Cat" would have been encountered at this stage as bosses.[citation needed]

Jade Gully was going to have three acts: "Emerald Clouds", "Wolf Den" and "Bamboo Transit".


  • Windy Hill from the video game Sonic Lost World takes many elements from this stage.
  • This zone was given more information than the rest of the zones shown on Sonic X-treme.
  • In some screenshots of the Fang the Sniper boss fight from this zone, Sonic can be seen doing his Spin Slash attack from this game.
