The Fun Arcade appears in the episode The Cent of Money. It is a place where Bikini Bottomites go and play games. There is also gambling in the arcade. Mr. Krabs came here with Gary to take money from the arcade. Apparently, teenagers as well as seniors go there on their free time. There is another Arcade in Bikini Bottom, it is called Bikini Bottom Arcade.
It looks like a big, neon, shiny building. The word "Fun" is in an arrow and "Arcade" is in big letters on the building. It is shaped like a bucket full of coins.
