Place it right after the awkward reveal, then follow it with the SpongeBob Disappointed sound for a double take, or let the SpongeBob Boowomp sound close the bit with a cartoon sting.
About this sound
This is a short Spanish voice clip of Patrick Star saying 'pobre cosita fea' in a slow, mock-pitying tone, lasting just under three seconds. It feels teasing and condescending, like a fake-sympathetic jab at someone who looks rough, and it lands as a playful insult rather than real cruelty. The line comes from SpongeBob SquarePants, in its Spanish dub.
