About 4-5 years ago when this pink-haired dancing girl exploded as a meme and there were a thousand edits using it, there was a version with a japanese song, sung by a woman, that was everywhere on YouTube etc. For the life of me I cannot find this version, and not being japanese, I have no idea what the song was about. It was just a super cute song that still sticks in my head, but I can't find it anywhere.
