Sulfur Cube block.

The idea is to expand the Sulfur Cube mob with a new resource system. When defeated, the Sulfur Cube drops a new item called a Sulfur Pellet, a small golden-yellow ball similar in shape to a slimeball. Nine Sulfur Pellets can be crafted together to create a Sulfur Cube Block, a solid physical yellow block. The Sulfur Cube Block has a unique redstone ability: when activated by a redstone signal, it becomes heated and dangerous, causing any player or mob that touches it to catch fire and take damage over time. When activated, it produces a special golden-yellow sulfur flame and yellow smoke particles, making it different from normal fire and soul fire. To protect against this hazard, players can use a new boot enchantment called Petroguard, which creates a protective barrier around the boots and allows players to safely walk across activated Sulfur Cube Blocks without taking damage. This creates a complete gameplay system: Sulfur Cube mob → Sulfur Pellet → Sulfur Cube Block → redstone-powered hazard → Petroguard enchantment, giving the Sulfur Cube a unique purpose in Minecraft.
