Knarfy's Ruined Sulfur
by Knarfy
Knarfy's Ruined Sulfur adds a sulfur-themed underground biome, variant cube toys and a TNT cube that explodes, all built for Minecraft 1.21.8 on Fabric.
What it does
The mod introduces an underground cave biome where sulfur cinnabar blocks generate naturally. Rare dry humidity zones appear in the same way lush caves do, and floor-to-ceiling pillars hold water pools rich in potent sulfur. Players can pick up placed blocks by right-clicking them, and sulfur dust feeds babies so they grow up after five minutes. Shears shrink or strip the variant creatures.
The minigame side centers on sulfur cubes that take a new form when a listed item is right-clicked on them. Each of the tennis, soccer, hockey, bubble and jukebox cubes moves in its own way, sliding, bouncing or drifting, and the sport variants can hit entities hard enough to launch them fast when the matching game rule is enabled. The mod is published for Fabric only, with files for 1.21.8 and the latest file 1.0.6 dated 2026-03-30. Installation covers the server and each player's game. Its code is licensed under the MIT License and is not open source.

The original concepts for all of these features come from the first Minecraft Live of 2026 and are designed to make these features completely dumb and hilarious. Textures…
