Balloon Boy, often shortened to BB, was introduced in Five Nights at Freddy's 2 in 2014, created by Scott Cawthon. The balloon holding animatronic became memorable for his repeated hello and hi voice lines and his giggling, which players learned to dread during the night shift. Clips of the greeting spread through FNAF fan videos, remixes and soundboards, where the line was detached from gameplay and reused as shorthand for a cute threat. It remains popular because even new listeners hear the tension between innocence and danger.
