To double your dating
This episode begins with Stan, Soos, and Wendy setting up for a party at the Mystery Shack (as a means of raking in money).
Dipper and Mabel pretend to barf on each other using silly string and Wendy eventually joins in.
Dipper promises Stan that he will not leave the stand.
As Dipper puts on a bow tie in his room (the uniform for working at the ticket stand), Mabel teases him for liking Wendy.
Soos (serving as the DJ for the party) makes a competition that whoever parties the hardest will win a crown.
Mabel competes against Pacifica Northwest, the meanest, most popular girl in Gravity Falls, to stick up for her new friends.

Meanwhile, Wendy joins the party (which is getting hyped up) and leaves Dipper alone.
As everything is prepared, Dipper runs into Wendy waiting for the bathroom and talk like "normal people" where they reveal some secrets such as Wendy looking like a dork and Dipper's birthmark. Once Wendy can use the bathroom, all the Dipper clones assault the real Dipper for not obeying the list and lock him in a closet, but he escapes and it eventually leads to a big clone fight. Dipper eventually melts them all, except for Tyrone. They decide that Tyrone will manage the ticket stand, while Dipper hangs out with Wendy. Dipper and Tyrone plan to create two more copies to take Robbie's bike so he'll run after it and leave Wendy with Dipper. As a slow song plays, Dipper is urged by Mabel in asking Wendy to dance.
