“BOO”是使用 FontVibe AI 创作的血滴字体文字效果。粗体深红字母，表面湿润暗红，长长的血滴末端凝成圆珠，在侧光下孤立于纯黑背景。

rendered in blood drip font style. Bold block letterforms soaked in deep crimson blood — thick viscous fluid dripping from every letter bottom, large tear-shaped blood drops hanging with realistic surface tension, long fluid trails running down each letterform. Photorealistic blood texture: deep crimson with subsurface scattering, wet glossy surface catching light, darker clotting tones at pooling areas. Pure black background. Horror aesthetic, gravity-driven, physically authentic. BOO as massive Halloween blood font letters, perfectly centered. Dark atmospheric background — subtle moonlit fog, faint deep purple glow at edges. Deep crimson blood dripping from every letter — thick viscous fluid, large drops, wet glossy surface. Halloween horror atmosphere: cold moonlight from above, faint bat silhouettes in deep background bokeh. Photorealistic blood texture. Genuinely spooky seasonal horror aesthetic.
