If you play Minecraft on either Java or Bedrock, the Chaos Cubed update is now live—bringing a new sulfur cave biome, multiple blocks, and a new mob that can change what it does based on the blocks it eats. Here’s what’s new, where to find it, and what to expect next.
What changed in Chaos Cubed (Java + Bedrock)
Mojang has released the Chaos Cubed update for both editions: Java version 26.2 and Bedrock version 26.30, dated June 16, 2026. The headline feature is the sulfur cube, a new mob tied to sulfur caves. Unlike typical Minecraft creatures, the sulfur cube can eat other blocks and then adjust its behavior and attributes based on what it consumed. The update also adds a new underground sulfur cave biome, including sulfur pools and additional sulfur-related blocks.
Alongside the new cave content, the update includes a new music disc titled “Bounce.” It’s located in minecarts with chests inside abandoned mineshaft structures found within sulfur caves. Mojang also added several new music tracks—Ebb, Home, Memories, Nightly, and Shores—used across the main menu, Creative Mode, and multiple biomes (including the sulfur caves listed among them).
Meet the sulfur cube: how it works and where to play
The sulfur cube is designed around experimentation. Feeding it different blocks changes how it moves and behaves. For example, consuming a wooden block makes it buoyant and bouncy, while eating wool makes it light and slow. The update also highlights special interactions: the sulfur cube can eat TNT, and it can absorb magma blocks as well.
To find the new content, players are pointed to sulfur springs in the overworld. Those springs are associated with sulfur and cinnabar blocks and noxious gas. Digging beneath sulfur pools can lead to sulfur caves, which include shallow pools of water and glow lichen, plus sulfur and cinnabar blocks, sulfur spikes, and the sulfur cube itself.
The update expands the building options with two new block sets found in sulfur caves: sulfur and cinnabar, each supporting its own full set. New sulfur spikes grow on these blocks, giving sulfur caves a distinctive look. Stepping on sulfur spikes is described as harmless, though they can still fall and hurt players in the rare case they drop.
New blocks, hazards, and what’s next for Minecraft in 2026
Chaos Cubed adds more than just cave scenery. A new potent sulfur block is tied to the update’s bubbly and hazardous atmosphere. Sulfur springs are described as bubbly (and nauseating), and potent sulfur can be placed beneath water to create hot bubbling pools. The patch notes also mention bubble columns and puffs of noxious gas, with a warning that the gas can trigger nausea in players and nearby mobs.
The update also introduces geysers as a vertical movement and landscaping tool. They form when a magma block is generated or placed under potent sulfur that’s submerged under 1 to 4 blocks of water.
Looking beyond Chaos Cubed, it’s the second of three major Minecraft updates planned for 2026. Earlier in 2026, the Tiny Takeover update added baby mobs and a golden dandelion item that prevents baby mobs from aging. The next major update is due this fall, the Dappled Forest update, which should bring autumn-like forests with orange, red, and yellow flora plus new wood types.
What players should know
- Chaos Cubed is available now on Java (26.2) and Bedrock (26.30).
- The sulfur cube is a new block-eating mob; its behavior changes depending on what blocks it consumes.
- Start with overworld sulfur pools/sulfur springs—then dig to reach sulfur caves.
- Sulfur caves contain the sulfur cube, new sulfur and cinnabar blocks, and sulfur spikes.
- Potent sulfur can create bubbling hazards and noxious gas; gas can cause nausea in players and nearby mobs.
- The “Bounce” music disc is found in minecarts with chests inside abandoned mineshaft structures within sulfur caves.
Expert View
Chaos Cubed feels built for players who like systems and experimentation: the sulfur cube’s block-eating mechanic turns resource gathering into gameplay, and the sulfur cave biome gives that mechanic a clear “home.” The added hazards (noisy gas from potent sulfur, the environmental risk around spikes, and geysers for movement) also make exploration feel more intentional. Overall, it’s a content-rich update that should reward both builders (new block sets) and explorers (new cave structure and audio loot), with the only real unknown being how well sulfur-cube interactions will hold up alongside popular mods.
