Put it just after the impact in an edit, then follow it with a cartoon slip for the fallout, keeping this clip as the reaction in the middle of the sequence.
このサウンドについて
This is a very short Spanish voice clip in which a speaker says 'Nos pegan', meaning 'they're hitting us', in a single urgent burst. The line feels panicked and comically dramatic, as if the speaker has just been caught in a scuffle and is calling out for help. It works as a sudden, over-the-top reaction to a hit, a tackle or a playful attack.
