Mother 3 is a loose sequel to EarthBound. It takes place on the "Nowhere Islands", a series of islands on Earth, and stars several characters, including Lucas, a young boy; Flint, a farmer and the father of Lucas and his older twin brother, Claus; Duster, a thief; Kumatora, a princess; Salsa, a monkey; and Boney, Flint's dog. The primary antagonist is the mysterious Pigmask Army, an army of people who wear pig-like uniforms, who suddenly invades the islands, subjugating its population. They create a variety of technologies, including Chimeras (creatures that consist of either multiple animals or machine-animal hybrids). The game switches perspectives between the main characters during several chapters.
