Warm and cold variant of sulfur caves/springs surface

Ok so how this works is when the sulfur caves is generated near a biome let’s specifically say any cold biome it has a unique change attributed to it which is more fog, faster geysers eruption 2x faster as a normal one, the water is in a constant tug of war which is freezing and melting over and over again but only on the surface. For the warm variant, instead of fog it becomes denser and in doing so the humidity from the sulfur water will spread to all the air inside the biome making it when you breathe the air there you slowly build up the effect of nausea and the only ways to remove it is by either leaving the biome or drink a milk bucket to refresh the buildup. This is all purely for the atmosphere and vibes for the drop since it still lacked somethings
