There exist a handful of Monster High dolls that are custom made for their owners by Mattel in celebration of an event. These dolls are one of a kind, but generally recycle the head mold and/or accessories. With one exception, the dolls are official, but the characters they represent are not. The two exceptions are Madison Fear and Grimmily Anne McShmiddlebopper, whose characters are official, but not fully owned by Mattel.
