Mikudayo is the chibi mascot counterpart of Vocaloid star Hatsune Miku, recognisable by her oversized head, blank stare and plush costume appearances at events. The character became a meme in her own right, spawning fan art, videos and short voice clips that exaggerate her cuteness for comic effect. This drawn out name call is shared alongside other cute anime catchphrase sounds like Tuturu, and it stays popular because a single squeaky shout instantly identifies Miku fandom, Vocaloid culture and playful otaku humour without needing any context.
