Dipper asks her "who thinks impressing" with all the pageantry. Pacifica gets Dipper changed into a tuxedo and helps him tie his bow tie. As Dipper looks around the mansion, Preston subtly whispers to his daughter, asking if Dipper is really going to be wearing his current attire, and she tells her father that she will take care of it. Preston speaks to Dipper, happy to see him and asking if he is sure that he can help fix their "problem." Dipper assures him that he can, and Preston is glad to hear it.
The five arrive at the Northwest Manor, and Mabel awes over how fancy everything in the mansion is, even going as far to touch the face of a butler, amazed by the family's "fancy man." She and her friends grab a gift basket (which is full of live quails) and happily run off as Preston and Priscilla Northwest approach Dipper and Pacifica. Pacifica welcomes Dipper and company to the Northwest Manor. Mabel then instructs Grenda and Candy to find the glue gun, as they will be making dresses. Pacifica begrudgingly hands him three invitations, which he accepts with a grin. She pleads him to help with the ghost problem, as it is an opportunity for her and her friends go to the party, which is their "dream." Dipper reluctantly agrees, and he returns to Pacifica, telling her that he will help if she gives him three invitations to her family's party. Mabel then runs to the open door, greets Pacifica and pulls Dipper aside. Dipper refuses to help Pacifica due to her disdain and cruelty to the Pines in the past.
There's a knock on the door, and Dipper opens the door to see Pacifica, who says that she needs his help. Afterwards, all three girls express interest in going to the party and say how much they envy Pacifica. Later, Dipper prepares for a marathon of Ghost Harassers at the Mystery Shack when Mabel, Candy, and Grenda interrupt him to watch the news coverage of the Northwests' party.
The three duck under the table for cover, and a newspaper falls by Preston, showing Dipper fighting a giant bat with a police taser, and Preston says he thinks he's found the perfect person to help with the Northwests' ghost problem. Suddenly, various objects around the manor start floating and attacking Pacifica and her parents. The Northwests are having a practice dinner for their annual party taking place the following day. Pacifica enlists Dipper’s help to rid the Northwest Mansion of a ghost before he wreaks havoc on her fancy party.
