fuwapuchi
FuwaPuchi is a line of character dolls by SEGA, designed by Sanpati, featuring Hatsune Miku as well as other Vocaloid characters and copyrights.
Also known as fuwas, or fufu in Chinese, they have distinctive large heads with solid oval black eyes, blush stickers, and a D-shaped smile (though other expressions exist). They come in various sizes ranging from charms to dolls large enough to wrap both arms around.
