The four Express Your Inner Monster dolls. Wonderful in theory, especially with all the fun accessories - you can see the peacock headdress & tail on the blue doll, & phoenix wings over on the right, and there are several more. But I have a major grump against Mattel here: the doll on the left has a plain body, not the skeleton covered with a translucent shell, because my doll only had half the shell! Mattel just shrugs & says “Tough!” (I papaphrase). Not good enough, these dolls are not cheap.
