Mrs. Forster is a strange old woman rumored to have magical abilities. When Sharon and her sister, Alice walk into a garage sale she's hosting, Sharon accidentally breaks one of her china bowls. In the form of a spider, Forster begins to stalk Sharon wherever she goes. Eventually, she attacks Sharon in her room, and uses her magic to shrink Sharon to the size of a doll.
Mrs. Forster finds enjoyment in tormenting Sharon. She wants revenge for the breaking of her bowl, and stops at nothing to get it.
Forster is described as having dark eyes, and a pale streak of hair.
