Put it right after the reveal or mistake in your edit, as the first reaction, then follow it with the Kiko laugh once the moment settles. For a second comic beat, add the Plankton ooooh before it as a slow lead-in.

This is a single clean human scream, one long drawn-out ahhh lasting about 1.4 seconds. It sounds raw and unfiltered, like someone letting out a sudden cry in the middle of a moment. The feeling is dramatic and over-the-top, funny when it is exaggerated and tense when it lands at a shocking moment, making a small reaction feel much bigger.
