AlaCraft's Sulfur Cube guide covers the mob from the Minecraft 26.2 "Chaos Cubed" update (Java 26.2, released in June 2026; Bedrock 26.30): all 12 archetypes by absorbed material, from bouncy slime to TNT, the underground Sulfur Caves biome where the cube spawns, and dispenser automation for survival farms. It includes an interactive 3D preview and a one-click archetype switcher.

The Sulfur Cube is a passive mob from the Chaos Cubed update, and this page covers it end to end.
The cube lives in a new underground biome, the Sulfur Caves. They are easy to recognise: yellow sulfur, red cinnabar and hot sulfur lakes. Cave spiders spawn down there too, so it is worth bringing a weapon.
The core mechanic is absorption. The cube eats a full solid block and takes on its physics, turning into one of twelve archetypes with their own speed, bounciness, friction and buoyancy — from bouncy on a slime block to explosive on TNT. Shears pull the block back out and reset the cube, but once a TNT cube has been lit, nothing can be taken out of it any more.
The page also has a three-dimensional preview, cards for every archetype, a tour of the biome and a section on automation: the cube responds properly to dispensers, so archetype swapping can be built as a machine. Useful details: a big cube is caught with an empty bucket, like a fish; a small one cannot be caught; it grows up in exactly twenty minutes, and a big one splits into two small ones when it dies.
