Create a smooth and soft box PvP arena in a clean natural style. The arena is a perfect square enclosed by four high walls. The ground should be soft, light green, smooth, and visually comfortable. Add red mushroom trees only at the corners and edges for a subtle magical touch. In the center, include a narrow, gently curved river (1–2 blocks wide) with soft edges. Include a simple raised spawn platform and a small wooden hut on one side. Use soft, natural lighting. Keep the whole arena minimal, clean, and perfect for PvP gameplay.
