This short clip captures R2-D2 letting out a loud, high-pitched electronic scream made of rapid beeps and whistles. It feels frantic and funny, like a tiny droid panicking in the middle of a disaster. The sound comes from the Star Wars droid, whose expressive beeps turn alarm into instant comedy for fans.
