Chaos Cubed

Chaos Cubed gives Minecraft’s underground a new kind of energy. Explore the yellow and red bands of Sulfur Caves, experiment with geysers, and meet the Sulfur Cube—a mob whose movement changes with the block it absorbs. New building sets and music round out the second game drop of 2026.

Released on June 16, 2026, the drop arrived in Java Edition 26.2 and Bedrock Edition 26.30.

Potent Sulfur and Geysers

Potent Sulfur

Crafted from 9 Sulfur blocks, or found in Sulfur Cave pools.
Bubbles travel through up to 4 Water source blocks above it, producing a gas cloud at the surface.
Creates a geyser when placed above Magma or Lava, with 1–4 Water source blocks above it.
- Magma produces intermittent eruptions; Lava produces a continuous eruption.
- Eruptions push entities upward.

EffectSprite Nausea Nausea

The gas from submerged Potent Sulfur applies Nausea.

Sulfur Spikes

Sulfur Spike

Hang as stalactites or stand upright as stalagmites. Multiple pieces form longer spikes.
Opposing tips can join; crouching while placing keeps them separate.
Hanging spikes can grow beneath Sulfur blocks and fall when their support is removed.
Thrown Tridents break them. 4 Sulfur Spikes craft into 1 Sulfur block.
Falling stalactites deal damage. Landing damage from upright spikes differs between Java and Bedrock Edition.

Mobs

Sulfur Cube

Sulfur Cube

A passive mob found in Sulfur Caves, attracted to blocks it can absorb.
Accepts a suitable block directly from a player or picks up a dropped block item.
Splits into two smaller cubes when killed. Small cubes can be fed Slime Balls to grow.
Large cubes can be transported in a Bucket.

Sulfur Cube Stone Sulfur Cube with an Absorbed Block

Absorbing a block stops the cube’s normal movement behavior and turns it into a physical object that can be pushed or struck.
The block changes its bounce, weight, friction, and movement through liquids.
Shears remove the block and restore its normal behavior.

Block Behaviors

Absorbed material	What changes
Loose minerals and soil	A balanced, buoyant cube
Wood	Faster movement and a strong bounce
Stone	Slower movement with a strong bounce
Metal	Slower movement and little bounce
Organic blocks	Faster movement with little bounce
Wool	A light, buoyant cube with high air drag
Ice	Low friction and no bounce, allowing it to slide
Shroom blocks	Slower sliding with low friction
Soul Sand or Soul Soil	High resistance and very slow movement
Honeycomb Block	Very high ground friction and a sticky feel
TNT	An explosive cube that can be ignited
Magma Block	Damages entities on contact

Java Dispensers can insert or swap blocks, shear out a held block, or release a bucketed cube.
In Java Edition, cubes can ride Minecarts but cannot enter Boats.
Primed TNT cannot be sheared out or transported in a Bucket. An exploding cube does not split into smaller cubes.
