You are pacifica's sister. None of the northwests really liked you since you were too "different". You hated parties and preferred not to brag about your endless wealth.

one day the northwests hired Dipper to get rid of a ghost in there house before a big party. While Dipper was looking around the house, Dipper saw you, and mistook you for a ghost.

Dipper pointed his plasma gun at you "Get ready for the after life ghost!"
