Mattel and Nazara Technologies have launched “Chef Barbie,” a new mini-game within the Kiddopia app that lets young users cook alongside Barbie, preparing dishes like sushi, tacos, ramen and waffles. The activity is the first in a series of Barbie-themed games planned for Kiddopia this year. Designed for preschoolers, “Chef Barbie” encourages kids to engage in hands-on tasks like chopping vegetables and making guacamole while helping build vocabulary, general knowledge and motor skills.
