Catnap is the purple, cat-like monster from Poppy Playtime, the horror game series where players explore an abandoned toy factory, and he became a fan favourite for his unsettling smile and sleep-inducing gas. This particular clip is not official game audio but a short fan-made scream made with a voice-changer tool, which is why it sounds cartoonish rather than menacing. Shared on meme soundboards, it has been picked up by creators making horror reactions, Poppy Playtime edits and Portuguese-language comedy videos, where its brief, over-the-top panic makes it easy to drop into almost any surprise moment.
