Catnap is the primary antagonist of Poppy Playtime Chapter 3: Deep Sleep, serving as the leader of the Smiling Critters and a loyal follower of The Prototype. Since the game's release, the character has become a massive hit in the meme community due to its unsettling wide-eyed grin and skeletal frame. Memes often contrast Catnap's supposedly friendly 'Smiling Critter' persona with his horrifying reality, or use his image to represent sleep deprivation, looming threats, or the 'scary cat' trope. Whether he's hiding in the shadows of the Playcare or being edited into funny, out-of-context situations, Catnap has solidified himself as a modern horror icon in digital culture.
