Sabrina The Teenage Witch (Sabrina The Teenage Witch #21)

At a carnival, Sabrina uses her magic to help Harvey win the rigged games. While claiming she's not jealous of Harvey and that he must have freedom to date whomever he wants, Sabrina uses witchcraft to make sure that any girl who expresses interest in Harvey suffers an unspeakable fate: she causes one girl to get her own private thunderstorm, dumps garbage on another girl, and ends by turning girls into frogs or making the earth swallow them up.
