If your little one is a fan of Mattel's American Girl dolls, you may want to consider a Prime membership. Or at least make sure yours doesn't expire anytime soon. Amazon announced a deal today with the toy maker for production of four live-action specials based on the brand's characters. What's more, the online retailer has the option to produce "multiple seasons of episodic content," too. This means that in addition to the popular dolls making an appearance in the specials, the dolls could star a new kids series on the way as well.
