Anti-Bikini Bottom is down in the deep dark sea. Everyone who lives in Anti Bikini Bottom is evil (excluding the anti counter parts of Plankton, Karen, Man Ray and the Dirty Bubble) who are the only good residences. The main food source is chum. The residents get a helmet to go above the ocean. Scary monster noises are also often heard and most of the residences have big black beady eyes with tiny white pupils.
