Last year, Mattel debuted its WiFi-enabled Hello Barbie to make playtime a bit more interactive. A connected doll needs an internet-friendly home, too. At this year's Toy Fair, the company is showing off just that. The Barbie Hello Dreamhouse gives the brand's namesake her very own smart home that actually connects to the internet and a companion app. That connectivity allows the toy to accept voice commands from kids for tasks ranging from flipping on the lights to operating the elevator. Because of course Barbie has an elevator... duh.
