Ghoul's Alive!

Ghoul's Alive! is an upcoming doll line, which consists of Clawdeen Wolf, Frankie Stein and Spectra Vondergeist in modified versions of their basic fashions. Clawdeen moves her head back, closes her eyes, and raises her arms while howling, Frankie lights up, revealing her ribcage and making sparking sounds giving the illusion she is "sparking", and Spectra's transparent parts light up as she produces ghostly sound effects.

They are expected for a 2013 release.

All three dolls have been released early in late November 2012.
