Place it right after the smelly food appears, then follow it with Eww Brother Eww to keep the joke going before cutting to the next shot. For a bigger build-up, open with Oh My God Wow, let the smell land, and save this clip for the final complaint.
About this sound
Krillin delivers a short, just under four-second Portuguese outburst about the smell of sardines, his voice rising in disgust as he reacts to something foul nearby. It lands as a blunt, over-the-top complaint that feels both grossed out and funny, the kind of line that makes a bad smell feel like a joke. The clip comes from a Kesyn & Skelter recording.
