Bikini Atoll

Bikini Atoll is a small island in the Marshall Islands, which is also located in the Pacific Ocean. Underneath, you find Bikini Bottom, which is the place where Spongebob Squarepants, Patrick Star, and a lot of other Bikini Bottomites reside.

Trivia

 * The island is actually real, but has been blown up to test nuclear explosives between 1940 and 50.
 * Unable to arrive back at the island when they most need it, David Hasselhoff gives Spongebob and Patrick back to their home.
