This short clip is a single bright 'nya' spoken in a high, playful cat-like voice that lasts under two seconds. It feels sweet, cheeky and instantly cute, like a tiny character demanding attention with a purr of delight. The sound lands as a light, affectionate reaction that makes a moment feel softer and more playful without saying anything else.
