Dusk 2 Dawn

Dusk 2 Dawn is an old convenience store in Gravity Falls, Oregon first seen in the episode The Inconveniencing. It was closed down after a "murder" took place. Dipper and Mabel visit this store with Wendy and her friends to see what lurks around in there. It turns out it's haunted by Pa and Ma's ghosts who used to be the owners of the store until they were struck down by double heart attacks after hearing a song from a group of teenagers that were outside of their convenience store.

The name of this store is an allusion to Quentin Tarantino's From Dusk Till Dawn. In the movie, the protagonists enter a bar and realize that it is inhabited by vampires.
