Sulfur Caves Geysers

I suggest adding two features to make the new Sulfer cave biome even more immersive:

• Sulfur Geysers (Surface Waypoints): Similar to how Azalea trees mark Lush Caves, these yellow, steam-emitting surface formations would let players know exactly where to dig down to find a Sulfur Cave. As a fun interactive element, the steam could occasionally launch players upward out of the Geysers.

• The Sulfur Crab (Unique Mob): A camouflaged, hostile mob native to the harsh cave environment. Standard undead don't fit the volcanic theme, but a crab with a high-knockback "steam burst" or pinch attack would be perfect. Defeating it could yield heat-resistant shells to craft specialized gear for hot biomes like the Nether.
