The Sun and Moon Animations meme stems from the vibrant and contrasting personalities of the Daycare Attendant characters in Five Nights at Freddy's: Security Breach. Representing two sides of the same coin—the hyperactive, rule-abiding Sun and the menacing, sleep-obsessed Moon—the duo quickly became a staple for internet creators. These animations often highlight the 'duality of man,' contrasting productivity with burnout or cheerfulness with chaotic energy. Beyond the gaming community, the template is widely used to represent mood swings, ADHD symptoms, or simply the transition from day to night activities in a humorous, relatable way.
