Mulgur is a squat, swollen kuo-toa whose body resembles a living blobfish dragged from an abyssal trench. His gelatinous cheeks sag around a puckered mouth, his brow bulges over tiny black eyes, and his pale body folds into soft, wobbling ridges that glisten with lake slime. He moves with a slow, pendulous sway until suddenly propelling himself forward with startling speed, like a dropped sack that has learned to sprint. His skin feels cold, damp, and faintly granular, like wet river clay. The contradictory impression is that his ugly, collapsing face becomes almost handsome when he performs, because his entire body settles into an expressive, radiant poise while he sings.
