Hello Kitty taking on the aesthetic of Jack Skellington from "The Nightmare Before Christmas." Hello Kitty's round face is now adorned with Jack's iconic skeletal features: blackened eye sockets, stitched mouth, and elongated nose. Her ears could resemble Jack's bat-like ears, with thin black stripes running through them. Instead of her usual bright colors, Hello Kitty's outfit now mirrors Jack's pinstriped suit, with a white shirt underneath and a black coat with thin white stripes. She might also be wearing Jack's bat bow tie and carrying a miniature version of Jack's skeletal dog, Zero. To complete the transformation, Hello Kitty's usually cheerful expression is replaced with a mischievous grin, perfectly blending the worlds of cute and spooky.
