Notes:

Based on this Dipcifica headcanon of tardisman14:
"Still sometime before they start dating, Dipper wants to find a way to help Pacifica get to know some of his other friends better. So he decides to invite her to movie night with him and Wendy. Pacifica’s anxious at first after hearing from Mabel about how Dipper used to have a crush on Wendy, but she accepts. Once they meet up, Pacifica, like Dipper and Wendy, immediately starts getting into making fun of the cheesy movies that play on the Gravity Falls Bargain Movie Showcase. Soon this starts to become a regular thing when all 3 of them get together. Dipper even gets the idea to start recording them riffing on these movies in their free time. They upload the about 1 video every 2 weeks during the summer and holidays."
