Balcony (3F)

The Balcony is found in the third area of Luigi's Mansion.

After Luigi collects 20 boos, he'll be able to pass out onto the Balcony. Once on the balcony Luigi will find a large ring of Boos out in the center. Before challenging the many boos, Luigi can water all of the plants to get himself a good deal of jewels and gold and such. After doing this Luigi can go to the center to see all 15 boos, the boos will group around Luigi and circle him round and round and get larger and larger until they all form into one enormous boo, named Boolosus, which Luigi will have to fight. He will have to first break apart Boolosus then suck up an Ice Elemental Ghosts and fire Ice Elements at the single boos flying around to freeze them so he can suck them up, after a while of this Luigi will finally be out of peril. After which a large treasure chest will appear and Luigi will find the Area 4 key inside of it.

The Balcony is a large open area with a lot of plants and benches and such around the edges. There are two large Pegasus statues one on each side of the balcony, each of the two being frozen to allow Luigi to suck up Ice Elemental Ghosts. Many lanterns line the outside of the balcony as well.
