Place this clip right after the grab or approach happens, then follow it with a bruh meme reaction for the freeze, and close the bit with a fail sound meme if the person backs away empty-handed.

This is a 12-second Portuguese voice clip of a man urgently warning not to touch the vagabundo and to give him a bag of chocolates instead. The delivery is loud, frantic and overprotective, which makes it feel funny and absurd rather than threatening, like a dramatic guard shouting over something completely trivial in everyday life.
