7-Helleven
From Blaseball Wiki
The Seven Heleven is an inter-dimensional chain of convenience store located in the Hellmouth area. While there are countless sightings of the store, they all appear to be the same location, as evidenced by the employee behind the counter being the same individual at every occurrence. There is no known physical location of the store, which randomly spawns throughout the region. Multiple investigators have tried and failed to understand the circumstances of the Seven Heleven's arrival, with only one clue to go on from star player Randall Marijuana, "Idk dude it just kind of is there when I got the munchies."
