Circus Baby debuted in Five Nights at Freddy's: Sister Location, released in 2016 as the fifth main game in Scott Cawthon's horror series. Voiced by Heather Masters, the character became one of the franchise's most recognizable animatronics because her polite voice hides a manipulative personality. Short lines like this one spread through fan edits, gameplay clips and soundboards, where FNAF fans reuse them outside the game as warnings, reactions and jokes between friends who know the character.
