The tuturu part is best known as the signature greeting of Mayuri Shiina in Steins;Gate, which turned a simple two-syllable chirp into a widely copied anime catchphrase. This version pairs that reference with a bark and a hello, so it circulates less as a straight anime quote and more as a mashup for pet edits, VTuber entrances and soundboard greetings. Clips built around Tuturu have stayed popular because the sound is short, unmistakable and easy to drop into unrelated jokes without needing any setup or context from the original scene.
