Place it right after the failed attempt in your edit, then add the wrong-answer sting to underline the mistake before a laugh closes the moment for the viewer watching at home.

Fallo is a brief 1.3-second reaction clip centred on a single word for a failure or mistake, delivered as a quick, pointed interjection. It gives a dry, knowing feeling, the kind of small laugh that follows a plan going wrong rather than a big punchline. It works as a short, sharp response when words would take too long.
