Build a toxic underground slime lab...

Build a toxic underground slime laboratory or swamp-based waste processing plant. The structure should feel industrial but overrun by hazardous chemicals and organic slime growth. Use a mix of metal, stone, and mossy materials combined with glowing green elements to simulate toxic energy. Include leaking pipes, dripping slime, and pools of glowing chemical waste made from water and green-toned blocks. The environment should feel damp and overgrown, with vines, moss, and slime spreading across walls and floors. Add broken containment areas, exposed tanks, and unstable structures to give the impression of a facility that has been abandoned after a containment failure. Lighting should be eerie and green-tinted, creating a dangerous and polluted atmosphere.
