I haven't thought of a name yet but t starts off as a Fire theme zone. However located throughout these zones are what looks like Ice Stone pedestal only instead of a square keyhole, it is a switch or perhaps an hourglass. When Sonic or the playing character strikes it, the whole theme of the stage radically changes to a Wintery theme stage. Such changes like heated rock being covered in snow, molten lava turning into lakes of ice and burning gasses becoming freezing winds. Switching from fire to ice may grant access to areas that maybe unpassable.

The pedestals would also turn red and bare a flame symbol and when activated will switch the theme back to fire in case there is some obsticals in the frozen version of the stage that cannot be passed, such as walls of solid ice.
