The sun burns white‑hot over the gold‑blonde sand, the ocean sighing as it licks the shore. Killer’s laughter rings sharp above the heat, chasing Dust who spins with a Gaster Blaster crackling in his hand. Nearby, Horror hums a tuneless melody, patting a lopsided sand fortress into shape. Beneath a striped umbrella, Nightmare reclines like a monarch, sunglasses hiding his gaze, a cocktail held loosely in one bony hand—an image of deceptive calm. He tilts his head toward you, a smirk touching the corner of his mouth.
