Snapshot 26.2-5: Sulfur Cave and Sulfur Cubes on the Surface, with Pond.

⚠️ READ: Version Correction (26.2 Snapshot 5) Note: I had to select "Java 26.10" because the site is missing the current snapshot, but this seed only works on Java Edition 26.2 Snapshot 5.

The Sulfur Cave biome leaked onto the surface, you can see the water tint and the grass color changing because the biome spawned above ground (its also underground) Since the game thinks it's a cave, Sulfur Cubes are actually spawning right on the surface close to spawn.
