This clip is taken from Il Leone Pancrazio, the Italian animated series about the lion Pancrazio, and it circulates online as a short reaction sound rather than as a full scene. Fans lifted the exaggerated heart attack moment because it works instantly out of context, needing no dialogue or setup to explain the joke. Shared through soundboards and meme edits, it has become a shorthand for comic shock and overreaction, especially in cartoon-style videos where a dramatic moment needs to land in just a few seconds.
