Sydney Opera

The  (more commonly known as the Sydney Opera House) is a famous opera house in Sydney, Australia that opened in 1973. Its design is based off a boat under full sail or a whole bunch of seashells. Luigi visits it during the events of Mario is Missing!, as the Sydney Opera Sheet Music containing Ludwig van Beethoven's had been stolen by Koopa Troopas. The plumber had to find it and return it to the opera. Upon completing his task, he is awarded a prize of 1,190 dollars.

Pamphlet information from Mario is Missing!
''Sydney's Opera House has become the most well-known landmark in the city. Most people remark that it looks exactly like a boat under full sail. A contest was held to design the Opera House. People from all over the world submitted plans, and a young architect from Denmark was chosen. Because of problems with the construction, the architect unhappily left the project before it was completed. The theater is built on Bennelong Point, named for an Aborigine, Australia's native people.''
