Marble Zone is the second zone in Sonic the Hedgehog, after Green Hill Zone. The zone combines the themes of ancient ruins, caves and lava. In contrast with the previous zone, Marble Zone involves more careful, slower-paced gameplay, such as requiring the player to negotiate moving platforms suspended by chains. The concept of switch-controlled doors is also introduced.
|| Leap across pools of red-hot lava and shifting islands. Then find the way to the underground palace where massive weights and flying balls of fire block your path.
| Caterkiller - Their body is protected by spikes. Jump on its head to avoid taking damage.
| Buzz Bomber - Found above ground.
| Batbrain - Found underground, suspended from ceilings. They will swoop down at you as you approach them.
| Suspended platform with spikes underneath. Found in underground areas, comes in various sizes.
| Fireball - Jumps out of exposed lava pools and holes in walls.
| Wall of slowly-advancing lava. Always moves to the right.
|| Early in production, Labyrinth Zone was going to be the second stage. But Labyrinth is much harder than the early stages, and it would have been a sudden spike in the difficulty. Sonic is really a different sort of action game compared to anything that had been made at that time, so we really wondered if it was OK to have him running through every stage so quickly, so we wanted there to be a moment for the player to catch his breath.

- In this zone is a particular graphic representing a pair of lions around a fountain, a stereotypical Greco-Roman idea. It somewhat resembles Mario from the Mario series of games, though this is likely a coincidence.
