The sound comes from the world of Shrek, the DreamWorks animated film series that began in 2001 with Shrek living alone in his swamp. That location became one of the most recognisable settings in the franchise, tied to his desire for peace and his famous warnings for others to stay out. Clips of its ambience circulate online as a shorthand for solitude, messiness and fairytale parody. Editors reuse it in memes, gaming videos and roleplay scenes because the setting is instantly understood even without any dialogue or characters on screen.
