This doll-shaped music player can hold as many as 120 MP3 or 240 WMA-file songs and links up to the Barbie Girls website, a virtual world in which the player acts as a real character. The site gives girls the opportunity to tailor their characters' styles, shop for clothing, decorate their online room and adopt a pet. For safety purposes, the website features information filters and only allows a 2,000-word limited vocabulary.
