ShakaCat シャカシャカポテト シャカポテ シャカシャカ ミクとシャカろ
An early 2024 advertising campaign by McDonald's Japan for their "shaka shaka" shake-in-bag seasoned fries (known internationally either as McShaker Fries or as Shake Shake Fries), typically featuring or referencing one of two anime cat girls shaking said bag to a rendition of Nyanyanyanyanyanyanya! (from either Danbooru post #7275638 or Danbooru post #7278645).
A 2025 iteration of the campaign would have Hatsune Miku as the anime cat girl shaking the bag (as seen in Danbooru post #8911236).
