Gothic Girl's Versions of Monster High Dolls

I was out shopping over the weekend and saw something I had not noticed before. In two different stores I saw dolls that looked like Monster High dolls but weren't. I didn't get a picture of the first dolls,but they came in two packs and were brightly colored. At the second store I saw another version of dolls by a different manufacturer. These Gothic Girls closely resemble Monster High dolls. The one in the box reminds me of Draculaura and the one on the box art looks a lot like Frankie. They are priced just a bit cheaper than a budget line Monster High doll, but it looks like the clothes should be interchangeable.
