She also happens to be buried in the cemetery near the gang's neighborhood and supposedly comes back from the dead every anniversary of the murder. Arnold, Gerald, Eugene, Harold, Sid and Stinky are scared twice by Helga and Curly, each pretending to be the Ghost Bride (Helga because she wanted to get back at the boys for not letting her come with them because she was a girl and Curly because he was jealous he didn't get to tell the story).
