Marshall Islands
Marshall Islands is another bunch of atolls and islands in Oceania. Their languages are English and Marshallese.
The islands were once a Spanish colony, until they sold it to Germany. In the World War I, they lost it, like their other colonies, to the Japanese. After World War II, their administration passed to United States, where they decided to make a few nuclear tests (actually, they even destroyed some atolls with the explosions… nukes are dangerous). The country declared independence in 1979.
Probably the most famous landmark of Marshall Islands is the Bikini Atoll (the type of swimwear was named after it, not the other way around) and its bottom, where SpongeBob SquarePants and company reside. Actually, considering the nuclear tests in the area, the sheer weirdness of Bikini Bottom should be a surprise to nobody.
