TOXIC AND CHAOS CUBED

The new mob, "RED SULFIDE SLIME" (which in real life is the mineral cinnabar), the primary ore of mercury. It could be hostile to the player, and when it hits them, it could inflict the poison effect (mercury is poisonous upon contact with a person) or the nausea effect (nausea is one of the gastric effects of mercury).

And a new mineral, "PRIMARY SULFUR" (a mineral that is the origin of sulfide, since combining sulfur with another mineral produces sulfide). This is a yellowish, almost whitish stone with small, highly saturated yellow crystals. It can be found under toxic sulfide tanks. This one is somewhat rare; you can find four to twelve ores per tank.

This new mineral will be used to make a new type of gunpowder called "BLACK POWDER." When used to craft regular TNT, it will create "BLACK TNT," which is twice as powerful as regular TNT. Additionally, four sulfur stones can be used to create "PURE SULFUR" blocks, decorative blocks that, when placed in contact with water, will form thermal pools (similar to toxic sulfur pools but without the nauseating effect).

Cinnabar crystals (forms resembling stalactites and stalagmites, but with a different shape) could also be added. These would grow on the ceilings and floor of the cave and would serve as the source of red pigment.
