Place this clip right after the reveal shot in your edit, then follow it with the Ceeday Huh sound for a second reaction beat, or switch to the Oh My God Wow sound when the reveal turns impressive instead of baffling.
このサウンドについて
This clip is a short voice recording of someone asking 'O que é isto?' in Portuguese, which means 'What is this?' in English. The line lasts just over four seconds and is delivered as a plain, puzzled question. It gives listeners a baffled, caught-off-guard feeling, like the speaker has just seen something they cannot explain at all.
