The Shiitake Dance is linked online to Juufuutei Raden of Hololive, whose fans clipped and reshared the cute mushroom chant as a short soundboard audio. Hololive VTubers often create repeatable bits during streams that fans turn into edits, and this one spread because the word shiitake is easy to loop, caption and dance to. The clip is now used far beyond its original fandom for lighthearted edits where a character, pet or object is made to look like it is happily dancing to the chant in time.
