Elvira, Mistress of the Dark, has returned to Knott’s Scary Farm for the California theme park’s annual Halloween festivities.

From now through the end of October, Elvira will appear in an all-new show that will also feature a merchandise signing event–Elvira's Boo-tique Experience. Fans who purchase at least $40 of Elvira merchandise on event nights will get to meet Elvira and have her sign one of their new purchases.

Knott’s Berry Farm’s themed Halloween events take place every weekend from now through Nov. 2 and on Halloween.
