Marble Zone

''See Sonic the Hedgehog (game) Marble Zone is a level in the first game, which comes after Green Hill Zone. It is a level with ancient buildings made of marble and an underground castle with spiky chandeliers. There is a lot of lava that can harm Sonic in this level. Certain bricks can be destroyed for points; sometimes up to 30,000 could be obtained, if the bricks are destroyed in sequence. At the end of Act 3, Dr. Robotnik attacks with an improvement to his craft that shoots fireballs on one of the two platforms Sonic can stand on, briefly setting it on fire. This zone also has many shortcuts, and walls that you can break through for rings and shields. An early version of this zone featured UFOs in the sky, but they were dropped for the final release.
