Build a BOX PvP arena spawn with a mushroom forest theme. The walls must be made of dark blackstone and deepslate NOT red brick, shaped organically with uneven height and bumpy terrain not flat square walls. Cover the walls and outer terrain with teal cyan and dark green foliage blocks to make it look overgrown. Add tall thin red brown pillars along the inside of the walls with fire on top. Scatter large exotic mushrooms of different heights and colors teal blue red brown both inside and outside the arena. The outer terrain should slope upward naturally like hills not flat. Add pink and purple moss coral and small plants covering the outside. The arena floor should be flat sand in the center. Make it look wild organic and overgrown not clean or symmetrical.
