Shrek has been one of the internet's most remixed characters since the early 2000s, after the DreamWorks film turned into a lasting meme staple. Short Shrek-themed alert sounds grew out of streaming culture, where creators replace default follower and subscriber notifications with funnier custom clips. This follower noise fits that trend, giving channels a recognisable comedic cue for new supporters. Its continued use comes down to instant recognition: almost everyone gets the Shrek joke, so the alert feels playful rather than generic.
