The Terrace is one of the areas found in the Treacherous Mansion of Luigi's Mansion: Dark Moon.
Appearance[]
The Terrace is a large balcony, with giant gargoyle statues overlooking the altar, and patches of grass on the sides with jack-o'-lanterns that give coins. The most notable feature is the golden altar in the back center. The Terrace's only access point is through the door in the Inner Courtyard. It can also be looked through the hole located in the Inner Courtyard and the windows in the West Corridor and East Corridor.
Dark Moon Quest[]
During Luigi's time in "Double Trouble", he can view the Terrace through the hole. However, the Terrace cannot be accessed in this mission.
In "A Train to Catch", if Luigi looks through the hole, he can see a Boo sliding on the altar. Another Boo appears and looks that the Boo who is playing. The other Boo tries to go back onto the altar after he is stopped by the other Boo, but pushes him back multiple times, and shakes his hand at him, upsetting him, and they fly off. Luigi can also access the Terrace, but he will never see the Boos. He can collect coins from the jack-o'-lanterns, but apart from that, there is nothing relevant here.
However in "Paranormal Chaos", Luigi needs to go there as E. Gadd discovered a strange signal from the Terrace. Then, Luigi discovers King Boo, and shoots purple electricity from his crown, creating a paranormal portal. King Boo laughs to himself as Luigi watches in shock, then he backflips into the portal. Just before Luigi can enter, several hordes of ghosts are unleashed through the portal and invade the Treacherous Mansion, and all must be captured unless their dimension will collapse upon itself. After Luigi clears the ghosts in the Space Exhibit, Nautical Exhibit, Jungle Exhibit, Ice Age Exhibit, Ancient Exhibit, Dark Age Exhibit, Kitchen and the Restrooms, Luigi must head back to the Terrace to fight the last large waves of ghosts. Although the port remains open for the entirety of the mission, it cannot be entered until the next mission.
After Luigi defeats King Boo in his own illusion, he is teleported back to the Terrace, and rushed over to his brother's painting, and E. Gadd is pixelated here too, and comforts Luigi and tells him to use the Dark-Light Device, to free his brother. Mario is freed and reunites with his brother, and the five Toad assistants are pixelated here with the Dark Moon pieces. Luigi is given a piece, and groups up with the Toads to restore the Dark Moon back together. The purple explosion from the Dark Moon returns all the ghosts back to their peaceful states once again. E. Gadd pushes a button on a remote to release all the ghosts out of the Ghost Container. 3 Greenies, a Slammer, a Hider, the Grouchy Possessor and the Polterpup join up with the Bros., E. Gadd and the Toads. A Slammer lifts Mario, 3 Greenies lift E. Gadd, and the Grouchy Possessor gives the Toads a ride. The Polterpup approaches Luigi, remorseful for his actions. Luigi forgives him, making the Polterpup happy and jumps into Luigi and licks his face. Mario compliments his brother for his actions, and with everyone happy, the Bros., E. Gadd, the Toads and the ghosts unite for a group photo.
In "Terrifying Invasion", the Terrace serves no relevant purpose and the paranormal portal is also closed.
In Luigi's Mansion Arcade[]
