Ever get sick of that plain old Barbie? Barbie’s now got an undead younger sister who is almost as popular as her predecessor. Goth Barbie is the second most popular doll and has achieved great success.

Mattel, who also makes the classic Barbie doll, came out with the new “Monsters High” line in summer 2010. Three years later, the eclectic dolls have achieved “monster” fame. According to UPI, the line has dolls like “Frankie Stein,” “Draculaura” and “Clawdeen Wolf,” which is supposed to appeal to girls ages 6 to 12. There are even zombie princesses like zombie Snow White and zombie Little Mermaid, NPR added.

"The message about the brand is really to celebrate your own freaky flaws, especially as bullying has become such a hot topic," Cathy Cline, who does marketing for Mattel, told the news site. "And it's also one of the fastest growing brands within the entire toy industry.”

Mattel was inspired by children’s new found love of Tim Burton and Lady Gaga, but the company didn’t know Monster High would become a billion dollar brand in just three years. "Honestly, it was very surprising to us. We just noticed girls were into darker goth fashion,” Kiyomi Haverly, vice president of design at Mattel told NPR.

Ironically enough, characters like Draculaura, who is Dracula’s daughter, are vegans who “can’t stand the thought of blood.” Haverly added, "Girls could really relate to that because that's part of what they're thinking of these days."

Twitter embraced the new line, and took to the social media site to share their acceptance of the new doll:
