Minecraft’s next feature drop is already shaping up to be one of the most unusual updates Mojang has tested in recent years. Across the latest Java snapshots and Bedrock 26.20 changelog, players are getting a detailed look at new underground biomes, experimental mob mechanics, new building blocks, explosive interactions, geysers, and accessibility improvements.
The update is currently being tested through Java snapshots and Bedrock beta/preview builds, meaning features may still change before full release. Even so, the direction is clear: Chaos Cubed is focused on playful physics, environmental hazards, and giving players new tools to experiment with in public Minecraft servers.
What Is Chaos Cubed?
Chaos Cubed is the name of Minecraft’s upcoming experimental feature drop, and the title fits the content perfectly. The update revolves around sulfur-themed world generation and a new mob that behaves differently depending on what players feed it. Mojang introduced the first Chaos Cubed features in Java Snapshot 1.
The headline additions include:
- Sulfur caves, a new underground biome
- Sulfur springs, surface features that hint at caves below
- Sulfur cubes, a new mob with block-absorbing behavior
- Cinnabar and sulfur block sets for builders
- Potent sulfur, which creates bubbles and nausea-causing gas
- Geysers, which launch entities upward
- TNT-filled sulfur cubes for explosive experimentation
- Closed captions in Bedrock Edition 26.20
For players who enjoy experimenting with mechanics, this update feels especially exciting. It is not just about new blocks or decorations. A lot of the new content is interactive, meaning it could affect farms, traps, minigames, adventure maps, and multiplayer events.
Sulfur Caves Add A New Underground Biome
One of the biggest additions is the sulfur caves biome. These caves generate underground and inside hills or mountains, creating a new reason to explore below the surface. Instead of simply adding another stone variant, Mojang is building an entire cave identity around sulfur, cinnabar, water pools, hazards, and the new sulfur cube mob.
Sulfur caves include bands of sulfur and cinnabar blocks, sulfur pools containing potent sulfur, and mob spawns such as sulfur cubes and cave spiders. Later snapshots adjusted the biome further, with Snapshot 4 adding granite and tuff mixed between sulfur and cinnabar blocks, while also making sulfur spike clusters slightly shorter on average.
For builders, this matters because both sulfur and cinnabar come with expanded block sets. Players can expect polished variants, brick variants, slabs, stairs, walls, and chiseled versions. That gives the update more value beyond exploration, especially for players who want bold yellow, orange, and red tones in their builds.
The Sulfur Cube Is Minecraft’s New Experimental Mob
The sulfur cube is easily the most unique feature in the Chaos Cubed testing cycle. It spawns in sulfur caves and can absorb blocks from players or nearby dropped block items. Once it has absorbed a block, its AI turns off and it becomes more like a physical object players can push, punch, move, or use in contraptions. Players can also shear the block out of the cube to reactivate it.
What makes the sulfur cube special is that the absorbed block changes its behavior. Mojang calls these behavior types archetypes.
Examples include:
- Wooden blocks: fast and highly bouncy
- Wool blocks: light, slow, and very bouncy
- Icy blocks: fast sliding with no bounce
- Shroom blocks: slow sliding
- Metal blocks: slow and flat
- Organic blocks: fast and flat
- Soul sand or soul soil: high resistance
- Honeycomb blocks: sticky with very high friction
This gives the mob far more depth than a normal slime-like creature. A sulfur cube can become a bouncing object, a sliding hazard, a sticky stopper, or a heavy obstacle depending on what it eats. In multiplayer, that could lead to obstacle courses, cube football games, puzzle rooms, and chaotic redstone testing.
TNT Cubes And Geysers Turn Up The Chaos
The later Chaos Cubed tests made the update even more unpredictable. TNT-filled sulfur cubes are a new way to create chaos, while geysers are vertical bursts of sulfurous water formed from potent sulfur, magma, and water.
Snapshot 5 expanded this with an Explosive sulfur cube archetype. When a sulfur cube absorbs TNT, it becomes immune to explosions while holding a block and can be primed through redstone, fire, flint and steel used by dispensers, or nearby explosions. Once primed, players cannot shear the TNT out, bucket the cube, or damage it.
Geysers are another major addition. They form when potent sulfur is above a magma block and submerged under one to four water source blocks. When active, they launch entities upward, which opens up several possibilities:
- Natural hazards around sulfur springs
- Vertical movement systems
- Parkour challenges
- Mob launchers
- Decorative hot spring builds
- Multiplayer minigame mechanics
Snapshot 6 continued expanding sulfur cube behavior with new Hot and Slow Bouncy archetypes. Magma-fed sulfur cubes become hot and can damage entities on contact, while another new effect makes cubes slower, heavier, and bouncier.
Bedrock 26.20 Adds Closed Captions And More
While much of the Chaos Cubed content is being tested across snapshots and previews, Bedrock Edition 26.20 also brings an important accessibility feature: closed captions. Mojang says captions include customizable positioning, duration, and sounds, making it easier for players to follow important audio cues.
The Bedrock changelog also includes bug fixes, sound tweaks, baby mob adjustments following Tiny Takeover, texture and geometry fixes, and UI improvements. That means Bedrock players are getting both experimental Chaos Cubed content and quality-of-life improvements at the same time.
Why This Update Matters For Multiplayer
Chaos Cubed looks like the kind of update that will reward curiosity. The sulfur cube alone has the potential to become a favorite for players who enjoy testing mechanics, building contraptions, or creating strange multiplayer challenges. Because it reacts differently depending on the block it absorbs, it is not just a new mob to find once and forget. It is a tool players can keep experimenting with.
Sulfur caves also give exploration a fresh purpose. Between cinnabar blocks, sulfur spikes, potent sulfur, geysers, and sulfur cube encounters, these caves feel more active than a simple underground biome. Builders get new colors and block styles, survival players get new hazards, and server communities get new opportunities for events, parkour maps, puzzles, and chaotic minigames.
If the current testing features make it into the full release, Chaos Cubed could become one of Minecraft’s most playful updates in recent memory.
