Place this clip right after the reveal frame in your edit, once the subject is fully visible. Lead into it with Oh My God Wow for the initial surprise, then follow it with the kids cheering sound to close a group celebration scene.
About this sound
A Portuguese voice repeats 'ai que linda, linda' — oh, how beautiful — for about fifteen seconds, stretching the vowels in a slow, sing-song delivery. The repetition sounds tender, delighted and playful rather than loud, giving listeners an immediate sense of admiration for something cute, pretty or heartwarming in front of them.
