CatNap is the main antagonist of Poppy Playtime Chapter 3 Deep Sleep, released in 2024 by Mob Entertainment as part of the indie horror series that began in 2021. The purple cat creature stalks the abandoned Playtime Co. factory and became a fan favourite among the Smiling Critters, inspiring gameplay clips, fan edits and scare compilations online. Its sudden screen-filling appearances made the sting a go-to horror cue alongside the FNAF Jumpscare Scream, and creators still reuse it to signal an instant, playful fright in gaming videos today.
