The dwarf princesses dolls interest be greatly, not only because of their spanish origin, but because of the skills they possess. The calca and brina (possibly a very difficult battle) can transform and combine, like Gurren Lagan.
So, while they are a bit creepy, they have an awesome theme song, but my main question is:
How do a bunch of dolls, no matter how magically powered up, nearly kill the party?
Seriously, considering they are probably made of porcelain or plastic, and are supposedly normal sized dolls, how do they almost PHYSICALLY beat up the party?
