The appearance of the Poisonous Mushroom King combines exquisite classical fantasy decorations with the mysterious elements of dark Goth. The top of his huge mushroom-shaped hat is inlaid with metal decorations like ancient crowns, and the outer layer is covered with green and purple corrosion spots. The edges of the mushroom hat are filled with intricate Gothic carvings, emitting a dim glow and occasionally spewing out toxic mists. The shape of the crown presents a ghostly outline, highlighting its evil and power. His robe was woven from mushroom skins and decaying plants, with a complex style. However, as the styles overlapped, the patterns of the clothes became more dark and textured, interwoven with the marks of death and decaying.
