All Sulfur Cube Blocks: Properties, Interactions, & More

Sulfur cubes are a unique mob introduced in the Minecraft 26.2 Chaos Cubed update. Found in the new Sulfur Caves biome, these passive slime-like mobs have a fascinating mechanic: they can absorb blocks they touch, changing their physical properties in the process. This makes sulfur cubes one of the most versatile and entertaining mobs in the game, especially for redstone engineers and mini-game creators.

This guide covers everything you need to know about sulfur cube block variants, how absorption works, and what you can build with them.

What Is a Sulfur Cube?

A sulfur cube is a passive slime-type mob that spawns naturally in Sulfur Caves. Unlike regular slimes, sulfur cubes do not attack the player. Instead, they hop around the cave absorbing blocks they encounter. When a sulfur cube absorbs a block, its appearance changes to match the absorbed block type, and its physical properties — bounce height, fall speed, friction, weight, and special effects — change accordingly.

Sulfur cubes come in three size variants (small, medium, and large), similar to regular slimes, but their behaviour depends entirely on the block they have most recently absorbed.

All 12 Block Types and Their Properties

Soccer Ball (Dirt/Clay)

When a sulfur cube absorbs dirt, clay, or similar earthy blocks, it becomes a Soccer Ball type. This variant is light and bouncy — it hops moderately high and has a noticeable bounce when it lands. Soccer Ball cubes are the most common variant since dirt is abundant in Sulfur Caves. They're great for basic bouncy platforms and parkour courses.

Rubber Ball (Logs/Wood/Bamboo)

Absorbing wood, logs, or bamboo turns the sulfur cube into a Rubber Ball. This variant is very light and very bouncy. It bounces significantly higher than the Soccer Ball and maintains its momentum longer. Players standing on a Rubber Ball cube will be launched upward, making this variant ideal for trampolines and elevation mechanics.

Balloon (Wool)

Wool-absorbed sulfur cubes become Balloon type. This variant is very light and slow-falling. Instead of bouncing, it floats downward gently after a hop. Balloon cubes are excellent for creating slow-descent platforms or decorative floating elements in builds. They can also be used in parkour maps to create sections where players drift across gaps.

Beach Ball (Stone)

Stone, andesite, granite, diorite, and similar stone-type blocks produce the Beach Ball variant. It is heavy and slightly bouncy. Beach Ball cubes don't hop very high and have a muted bounce. Their weight makes them useful for pressure-activated redstone contraptions where consistent weight is needed.

Medicine Ball (Ore/Metal)

Ore and metal blocks (iron, gold, copper, netherite, etc.) create the Medicine Ball type. This variant is heavy and fast-falling. It drops quickly after hopping and has almost no bounce. Medicine Ball cubes are dense and can activate heavy pressure plates from a greater height than lighter variants.

Golf Ball (Sponge/Plants)

Sponges, grass blocks, leaves, and other plant-type blocks make the Golf Ball variant. It is slightly slippery, fast, and slightly bouncy. Golf Ball cubes slide a bit when they land and maintain good speed. This variant is useful for water-adjacent builds since it retains some bounciness while being less floaty than the Balloon type.

Boulder (Soul Sand/Soil)

Soul sand, soul soil, and netherrack produce the Boulder type. This variant is very heavy and has no bounce. Boulder cubes barely hop at all and land with a thud. They're excellent stabilisers in redstone contraptions where you want a weight that doesn't bounce out of position.

Hockey Puck (Ice/Snow)

Ice, packed ice, blue ice, snow blocks, and powder snow turn the sulfur cube into a Hockey Puck. It is slippery and has no bounce. Hockey Puck cubes slide across surfaces similarly to entities on ice, making them difficult to predict in builds. They're perfect for ice-based mini-games or chaotic redstone setups where movement needs to be unpredictable.

Curling Stone (Mushrooms)

Mushroom blocks (red, brown, nether, and warped fungi) create the Curling Stone variant. It is slippery, slow, and has no bounce. Curling Stone cubes move deliberately and slide gradually to a stop. Their slow, predictable movement makes them good for timing-based contraptions and decorative builds in mushroom-themed areas.

Dart (Honeycomb)

Honeycomb and honey blocks produce the Dart type. This variant is sticky. Dart cubes stick to surfaces they land on and can hold entities or items in place momentarily. They behave similarly to honey blocks but in mob form. Dart cubes are excellent for item transport systems and sticky traps in adventure maps.

Hot (Magma)

Magma blocks and nether-related heat blocks create the Hot variant. This type is damaging — touching a Hot sulfur cube deals damage to the player, similar to touching a magma block or campfire. Hot cubes emit small smoke particles and have a faint glow. Use them in traps, hazard courses, or decorative nether-themed builds.

Grenade (TNT)

TNT blocks produce the Grenade variant. This type is ignitable — when a Grenade sulfur cube is lit with flint and steel, fire charge, or a nearby explosion, it detonates after a short fuse time. The explosion radius and power match a standard TNT block. Grenade cubes are highly dangerous but incredibly fun for PvP maps, traps, and explosive mini-games.

How Absorption Works

A sulfur cube absorbs blocks as it hops around. When the cube comes into contact with a block, it checks the block type and, if it's one of the absorbable types, the cube's appearance and properties update. The cube does not consume or destroy the block — it simply reads the block's data and applies the corresponding properties.

This means you can guide a sulfur cube through specific blocks to change its type intentionally. Build a path of blocks you want the cube to absorb, and it will transform as it travels. This is the foundation of sulfur cube-based contraptions.

How to Change a Sulfur Cube's Block Type

Changing a sulfur cube's type is simple: push, guide, or lure it into contact with the desired block type. Methods include:

• Water streams — Use water to push a sulfur cube across a floor of target blocks.
• Pistons — Push blocks into the cube or push the cube into blocks.
• Minecarts — Transport cubes in minecarts and unload them onto specific blocks.
• Natural movement — Let the cube hop around and place target blocks in its path.

Redstone Interactions

Sulfur cubes have several redstone-relevant properties:

• Weight-based activation — Heavier variants (Boulder, Medicine Ball) activate weighted pressure plates from greater heights.
• Bounce timing — Bouncy variants (Rubber Ball, Soccer Ball) can be used in timed circuits where they trigger plates at consistent intervals.
• Sticky mechanics — Dart cubes interact with sticky pistons and honey blocks for item movement.
• Explosion detection — Grenade cubes can be used as disposable explosive triggers in trap circuits.

Creative Uses for Mini-games

Sulfur cubes open up many possibilities for custom maps and mini-games:

• Bouncy parkour courses — Use Rubber Ball and Soccer Ball cubes as jump pads.
• Slow-fall zones — Balloon cubes create sections where players drift across gaps.
• Ice hockey mini-games — Hockey Puck cubes on ice make a chaotic puck for player-vs-player sports maps.
• Explosive obstacle courses — Grenade cubes add danger to parkour courses.
• Weight puzzles — Combine heavy and light cubes on pressure plates for puzzle maps.

Conclusion

Sulfur cubes are one of the most creative additions in the 26.2 Chaos Cubed update. With 12 distinct block types, each offering unique physical properties, they provide endless possibilities for redstone engineers, map makers, and survival players alike. Whether you're building a bouncy parkour course, a complex redstone contraption, or simply enjoying the chaos in Sulfur Caves, understanding each block type is key to mastering the sulfur cube.
