I've never seen this before, so since there was only one box at my local Walmart, I got it to see how well they mixed with my MH dolls.
This is the candy colored Bratzilla. We'll call her SAW (switch a witch).
-SAW heads fit fine on a MH body, though the reverse is a little loose.
-Only male MH arm parts hybrid with SAW arm parts without modding (female arm part pegs are all too small).
-Male MH thighs are too large, and only stay on in a standing position. Female MH thighs fit pretty well, but are much shorter than SAW legs. I don't know if female MH lower legs fit the SAW thighs, since I have none on hand. The Male MH lower leg pegs are too large for the SAW thighs.
-Female MH arms fit in the sockets, but look a little wonky. Male MH arms fit really well, though. If you ever wanted a muscular 1/6 with minimal modding, now's your chance!
-The plastic overall is mixed when it comes to modding. The head is the typical soft vinyl and the body is hard. The limbs, however are softer, which means they can't be sanded, but does give them a vinyl-ish feel, which is interesting.
-She came with quite an extensive outfit, including a wig that fits very nicely on MH heads.
This set does come with two dolls and outfits, though I only plan on keeping one, which is why she isn't shown. Overall, I'd say she's a nice doll. No MH to be sure, but has a surprising level of compatibility with MH parts. n_n
