Additions

26.30 block and item additions

Blocks

Cinnabar

A red-colored block that generates in sulfur caves.
Used to craft or cut cinnabar stairs, slabs, walls, polished cinnabar, stairs, slabs, walls, cinnabar bricks, brick stairs, brick slabs, brick walls, and chiseled cinnabar.

Sulfur

A yellow-colored block that generates in sulfur caves.
Used to craft or cut sulfur stairs, slabs, walls, polished sulfur, stairs, slabs, walls, sulfur bricks, brick stairs, brick slabs, brick walls, and chiseled sulfur.

Potent sulfur

A variant of sulfur that emits bubbles when placed underwater. It also produces a cluster of noxious gas particles at the water's surface.
Players and mobs get Nausea when they enter water that is near and directly or indirectly connected to the block.
When placed above a magma block or lava source block and under 1–4 water source blocks, it creates a geyser.
- Magma blocks make the geyser erupt at roughly 50 second intervals, shooting a plume of water particles upwards and applying an upward impulse to entities above it for 4–5 seconds.
- Lava, on the other hand, will make the geyser erupt continuously.
- Entities directly above the potent sulfur block during an eruption will be launched into the air, but will not take damage from the eruption.
- The height of the plume and how high anything gets launched depends on the number of water blocks above the potent sulfur blocks, with the total height being about 7 blocks above the potent sulfur block for each water block.

Sulfur spike

Generates naturally on sulfur blocks inside the sulfur caves biome.
Forms a stalactite if placed on the ceiling or a stalagmite if placed on the floor.
Can be combined to form longer stalactites and stalagmites.
Stalactites and stalagmites merge if the tips are next to each other, unless placed while crouching.
Stalagmites will break if not attached to something below.
Stalactites fall down if not attached to something above.
Being hit by a falling stalactite or falling on a stalagmite deals damage.
Thrown tridents break sulfur spikes.
4 sulfur spikes can be crafted into a sulfur block.

Items

Music disc

Added the "Bounce" music disc by fingerspit.
- Has a chance of being found in mineshaft chest minecarts that are located in a sulfur cave biome.
- Has a comparator output of 8 when played in a jukebox.

Sulfur cube spawn egg

Used to spawn a sulfur cube.

Bucket of sulfur cube

Obtained by using a bucket on a sulfur cube.
When used, spawns a sulfur cube.

Mobs

Sulfur cube

A passive slime-like mob that spawns in sulfur caves.
Immune to fall damage.
When killed, it will split into 2 small cubes, like other slime-like mobs.
- Unlike the slime and magma cube, the small versions can grow up into the large version, like how a baby mob works.
It is attracted to the dropped item form of full blocks. The cube can pick up a block, or a player can use a full block on the cube, causing the cube to absorb it into its body.
- In this state, they become immobile and cannot be damaged by most entities. Instead it will be knocked back when attacked.
  - The knockback also depends on the damage that would have been dealt, with stronger attacks sending the cube further.
- Shearing it removes and drops the block, reverting back to normal.
- Depending on the full block, they will behave differently when punched while in its immobile state, examples are:
  - Blocks of iron make it heavy, i.e. it will have higher gravity.
  - Wool makes it floaty, i.e. it will have lower gravity.
  - Wooden logs and stems make it bouncy.
  - Ice reduces its friction, making it slide more.
  - TNT makes it able to be ignited and explode, with a fuse time of 6 seconds.
  - Stone makes it bouncy, but does not go very far.
  - Magma blocks make it so that entities that came in contact with it would take damage.
Can be caught in buckets to move it.

Music

- "Memories"
- "Ebb"
- "Home"
- "Shores"
- "Nightly"

Sulfur pools and sulfur spike clusters also generate here.

Greenish pools that generate in sulfur caves.
Consists of a body of water surrounded by sulfur blocks and cinnabar with potent sulfur generating at the bottom, which inflicts Nausea to mobs in the pool.

Sulfur spike

Clusters of sulfur spikes on sulfur that generate in sulfur caves.

Sulfur spring

A cluster of sulfur, sulfur spikes, and other rocks with a small sulfur pool on the surface.
Generates on the surface indicating the presence of sulfur caves below.
Contains magma blocks and potent sulfur, creating a geyser in the sulfur pool.

		Uh-oh.	Have a Sulfur Cube absorb a TNT block.	Specifically, you must press the use button to directly put the TNT into the Sulfur Cube, as dropping the TNT on the ground and having the Sulfur Cube absorb it itself does not trigger the achievement.	10	Bronze

Seed templates

Added the "Sulfur Cave" seed template.
