- - - - - Notes - - - - - Stone Yard Zone is a valley of Stone and Grass. It also has lots of hidden mines, and only about 9% were discovered. It's wildlife vanished, the plants disappeared, the mountains grew. Stone Yard becomes the coldest, foggiest, and the most dangerous zone to enter into. We have no idea how this happened, but it sure is Dr. Eggman's doing. - - - - - Credits - - - - - @UltraSonicGamer for assets and inspiration.
