The Famed Bikini Bottom Opera House is a large marble building. It was dubbed "the pinnacle of grown-up culture" by Squidward and is also visited by "mature" Patrick. It is only shown/visited in the episode "Squidward's School for Grown-Ups."
The Famed Bikini Bottom Opera House is what is stated a large marble building with many columns (6 to be exact) in front of the building. It also has many stairs which leads into the building itself. It's location is unknown but it may be located a few miles away from the Art Museum.
The inside of the Opera House is very nice. It has a very unique design mainly of the colors gold and green. It has many seats (including "box seats" that Squidward and Patrick sit in) and a stage which performers sing on. It appears that an opera singer always opens the show with a few lines before the actual show begins.
- The Famed Bikini Bottom Opera House may be based on another famous opera building: The Sydney Opera House.
- SpongeBob is the only person to sing in the Opera House as there is usually a whole crowd singing a performance.
