Giggle was introduced with Doors Floor 2, The Mines, the 2024 update to the popular Roblox horror game Doors, first released in 2022. Unlike the main floor enemies, Giggle clings to ceilings and drops onto players, with its laugh acting as the main audio warning before an attack. Clips of encounters spread quickly through Roblox gameplay videos and shorts, and the sound was soon lifted for edits, soundboards and memes. It remains popular because players instantly recognise the danger it signals, even without any visuals.
