Sonic Fanon Wiki

Marble Mountain is a zone from Bolt the Hedgehog. It is located on Northern Island.


Marble Mountain is a mountain that towers over Northern Island, and can be seen anywhere from the island. It is made of purple and gray rock, and has various zipline transports. Fans believe Marble Mountain is an homage to Hilltop Zone from Sonic the Hedgehog 2. There is a hidden caldera underneath, waiting to blow and turn Marble Mountain into a volcano.


Marble Mountain is relatively cool, and the air is crisp and clean. Act 2 is snowy and icy, but maintains the ziplines.


In Bolt the Hedgehog, after Act 2, Bolt arrives at the mountain summit, and encounters the only boss in the game not made from dark energy: Mountain Demon.
