Bikini Atoll is the marker of where Bikini Bottom is located. It first appears in the episode "Home Sweet Pineapple." It is a sand island in the middle of the ocean. Its most notable landmarks are the three trees that inhabit one side of the island. It appears small, but in reality, it is much larger and appears small because of an optical illusion.
