You mouth is wide open but you have as your face resembles a goldfish. Your eyes look like bear ears due to the lack of color. And because your appearance was so sudden a soon as you were there, you disappeared. But the sound you made sounds like an Mp3 file of a man who stubbed their toe bass boosted

Eri: "AH!"
