- This zone is not to be confused with Marble Garden Zone, which was frequently called "Marble Zone" in the comics.
The Marble Zone is a region consisting mostly of trees, ruins, and magma deposits that has been visited on a number of occasions by Sonic the Hedgehog.
Sonic the Hedgehog visited this area after passing through Green Hill Zone on his very first adventure to stop Dr. Eggman and his assistant, Dr. Julian Snively, when the two mad doctors came to South Island to strip-mine and process the island as part of their plan for world domination. From here, he chased them down to Labyrinth Zone. (VG: StH1, SSD: #12)
