Dead Eye Gulch was the name of Bikini Bottom at the time where Dead Eye Plankton owned most of it. The town appeared in the episode Pest of the West. Until Dead Eye Plankton came, it was called Bikini Gulch.
It is unknown when the settlement was established. During the western days an Easterner, Dead Eye Plankton, ravaged the town of its property and assumed ownership of each building until only the Krusty Kantina remained. When SpongeBuck arrived in town for a fry cook job, he was unwillingly appointed as sheriff. However, when he actually did defeat Dead Eye, Dead Eye Gulch returned to Bikini Gulch and developed to its modern structure.
There were only nine establishments running at the time.
