Originating from the 2021 release of Five Nights at Freddy's: Security Breach, the Daycare Attendant—switching between the friendly, hyperactive Sun and the terrifying, night-hunting Moon—became an instant fan favorite. The character's drastic shift in personality when the lights go out serves as the perfect visual metaphor for extreme mood swings, Jekyll and Hyde situations, or sudden realizations. On social media, users leverage this template to contrast their 'customer service persona' with their 'inner exhaustion' or to show the transformation of a situation from bright and happy to dark and chaotic. Its popularity exploded on TikTok and Twitter, where fans use the dichotomy to represent everything from caffeine crashes to the transition from the weekend to Monday morning.
