SpongeBob and Patrick play a pirate board game based on a real treasure map. Mr. Krabs joins in and wins a bunch of times in a row. The next day, Mr. Krabs takes the two boys on a treasure hunt, but they find out later that Mr. Krabs is using the game as a map, and is going crazy trying to find the Flying Dutchman's treasure.

Sandy gets homesick, so SpongeBob and Patrick do as much as they can to cheer her up. When they want to throw her a surprise party and she won't come, SpongeBob and Patrick make Sandy chase them to the Krusty Krab, where the party is being held.

Patrick introduces SpongeBob to a carnival but this "carnival" is really colored fishing hooks dropped by fishermen on land. Mr. Krabs warns SpongeBob to stay away and how dangerous they are, but Patrick keeps on talking about how fun they are. Who will SpongeBob listen to, Patrick or Mr. Krabs?
