The sound comes from One Piece, the long running manga and anime series created by Eiichiro Oda. In that world, Den Den Mushi are living snail phones, and their calls are signalled by a repeated poro poro poro sound instead of a normal ringtone. Clips of the call spread online as ringtones, edits and soundboard buttons, especially among anime fans who recognised the reference instantly. It stays popular because the loop is distinctive, easy to recognise in a few seconds, and useful whenever a creator wants a phone call to feel unmistakably cartoon and anime styled.
Über diesen Sound
Poroporoporo is the looping poro poro ring of a Den Den Mushi transponder snail from One Piece, used for anime call scenes, edits and joke phone moments.
Poroporoporo is a looping ring made entirely of soft, rounded poro sounds repeated in a steady pattern. The call starts simple and keeps cycling, so the longer it plays the funnier and more urgent it feels. It has a squishy, cartoon quality rather than a harsh phone tone, which makes even a normal scene sound like an important anime transmission is coming through. Viewers instantly read it as someone trying to get through, and the repetition builds a small moment of suspense before whoever is calling finally speaks or something goes wrong.
