The sound is credited to Donald Duck and the Gorilla, the Donald Duck cartoon released on March 31, 1944, where animal noises help sell the chaos of an escaped gorilla loose in Donald's house. Like many Golden Age cartoon effects, this growl was later lifted as a clean stock clip and shared on soundboards and in video editors. Its old cartoon texture sets it apart from modern wildlife recordings, so creators still reach for it when they want a scary animal moment that also feels playful and nostalgic.
