The pirate queen looks exactly like Sandy, except she wears a dark green dress, a dark gray coat, a dark gray pirate hat with a gold earring on it, dark gray boots, a red headband on her head, and a left black eye patch.
Role in episode
She invaded Mr. Krabs' cargo ship with her crew but was eventually stopped by him and then taken to the brig. However, Mr. Krabs gave her a pie with a candy key inside it.
