Sulphuric Blob

The sulphuric blob is the sulphur cube's slime ball equivalent. Small sulphur cubes will drop these at the same rate normal slimes drop slime balls. This creates an interesting form of investment, akin to animal husbandry.

Right-clicking it on farmland will fertilise it, as sulphur is a real-life fertilising agent, allowing for some amount of education in the game. Fertilised farmland increases the tickrate of the crop above it.

Sulphuric blobs can also be crafted into sulphuric heaps - a semi-transparent block that the player will slowly sink through, while providing a small boost to health regeneration.

Hostile Sulphur Cubes

Sulphur cubes are now hostile, providing a unique threat to the caves. Sulphur cubes will still behave exactly the same as before, however they'll active hunt down the player. If any edible block is dropped, they'll begin to target that, instead.

If an eating sulphur cube gets knocked into an entity, that entity will take damage, scaling with the velocity of the sulphur cube. This will allow for combative player expression, where players can feed a sulphur cube a certain block, and launch it into the horde of mobs following them, ricocheting like a pinball.

Sulphur cubes can now be made non-damaging. This is done by feeding them a bucket of milk, "diluting" their density. They'll just follow you, much like small slimes. All behaviour is retained after diluting a sulphur cube, with the only difference being that they will no longer deal damage.
