Party at the Mystery Shack

The Party at the Mystery Shack was a large dance party that took place at the Mystery Shack. It was no one's birthday, but Grunkle Stan decided to throw the party when he needed more local kids to come to the Mystery Shack and buy merchandise. It is unknown if his original plan worked, but the party had a large turnout.

History
Mabel decides that the party is her opportunity to make friends. At the party, Mabel meets Candy Chiu and Grenda. She stands up for them when they are bullied by Pacifica Northwest by competing against her for the title of Party Queen, which Mabel subsequently loses after Pacifica cheats to win. But Candy and Grenda don't care, and then they have a slumber party.

Meanwhile, Dipper makes clones of himself using Grunkle Stan's copy machine so that he can be at two places at once; the ticket booth and on the dance floor with Wendy.

Trivia

 * The party had a $15 exit fee.
 * The flyers to the party said "Free?" on them; however, there was still an exit fee.
