Mattel teamed up with CookieSwirlC on a new line of dolls designed in collaboration with the popular YouTuber.

Launching in December, exclusively at Walmart, the line includes the Lotta Looks collection and the CookieSwirlC Barbie doll and play set.

The CookieSwirlC Lotta Looks collection is inspired by social trends and features mix-and-match, plug-and-play pieces that kids can use to create more than 100 moods and looks. In addition to a host of clothing options and accessories, the dolls include interchangeable facial pieces that kids can use to transform each character’s expression. Characters include Rainbow Sugar Rush, Candy Cub, and Chocolate Chip Chill. Additional Mood Pack accessory sets are sold separately.

The CookieSwirlC Barbie doll and play set brings the YouTuber to life as one of Barbie’s friends — complete with a branded t-shirt and her dogs. The included play set includes a workstation with everything a YouTuber needs including a pretend camera, laptop, and smartphone, along with three mystery boxes each containing a unique surprise. The set also includes three diorama scenes to use as a stage to present stories as kids pretend to be a digital content creator.

Mattel’s CookieSwirlC Lotta Looks collection is expected to ship on or about Dec. 11, while the CookieSwirlC Barbie is hitting stores now.
