Giant enchanted red mushroom building, ~75 blocks tall with a ~60-block hollow stem. Stem starts ~30 blocks diameter, narrows organically to ~26-28, then dramatically widens beneath the cap. Make it irregular, asymmetrical and naturally grown, with subtle bends and bulges; NOT a cylinder or stacked circles. Stem palette: mushroom stem, calcite, bone blocks and stripped pale oak logs, irregularly mixed. No floors, stairs, windows, furniture or decorations. Huge overhanging organic mushroom cap with irregular edges, made from red concrete with large uneven white concrete spots. Cap should be thick and hollow with room for a restaurant. Fantasy/enchanted aesthetic; prioritize dramatic organic silhouette.
