Bikini Bottom Civil War

The Bikini Bottom Civil War was a war between Luan (In Sandy's body) and The Magic Hat (In Patrick's body). It was the first war that Thomas and Runnervous fought in their new powerful form known as Thomervous. Luan and The Hat merged back into The Luan Hat, leaving Patrick and Sandy to pass away from natural causes. As an outcome of this war, Luan became pregnant with SpongeChris, though both her soul and the hat would later melt away upon his birth.
