Mamma Jacobs (first name unrevealed) is the mother of former jockey and presumed "ghost", John Joseph Jacobs. When first she appears, she seems nice and forgiving towards Olive, who won the Jock-Off 2000. It turns out, however, that she was actually trampling those involved with the sabotaging of her son's girth, disguised as the ghost of her son. She appears in "Girth".
