The Flying Dutchman is a dead pirate, and he possesses a huge golden treasure. The Dutchman is considered the terror of the Bikini Bottom; he is the green ghost who haunts the underwater city. He is not an inherently bad creature; he only gets mad when someone impersonates him. The Dutchman was named after the famous ghost ship of the same name. It was said that The Dutchman haunts because his body was not put to rest after he died, and a thunderstorm occurs whenever he appears in Bikini Bottom.
