Need Help Identifying Barbie with Side Gear

Question

Hello,

Need help in identifying unique looking Barbie Doll.

The doll has a gear on her right side and button on her back. I'm not sure what she attaches to or what she does.

The back is marked:

"Â©ï¸2010 MATTEL MADE IN CHINA."

Thanks,

Cutie-Boots
