Summerween (event)

Summerween is a day celebrated only in the town of Gravity Falls, Oregon. It is celebrated because the residents of Gravity Falls loved Halloween so much that they celebrate it twice a year, But it was renamed Summerween since it is celebrated in the Summer. Thats why they use jack-o-melons instead of jack-o-lanterns.

Summerween Activities
Everyone in Gravity Falls celebrates the holiday like its Halloween. They light up there jack-o-melons and dress in costume, then they give out the candy. Mabel was very excited to go trick-or-treating for the last year. But Dipper wasn't so excited because he wanted to go to Tamby's party so he could hang out with Wendy until the Summerween Trickster showed up.
