Boo's Mansion is the home of some Boos in Paper Mario. Lady Bow and Bootler live here, as well as many other Boos. Mario needs to go through Forever Forest to get here. Down the road from Boo's Mansion is a windmill, Gusty Gulch, and Tubba Blubba's Castle.
The mansion consists of puzzles and traps that Mario must solve and get through to even greet Lady Bow. It has three floors.
In Paper Mario: The Thousand-Year Door, Boo's Mansion (though referred to only as "the mansion") is briefly mentioned by Bow, who appears (alongside Bootler) at Poshley Heights after the game is beaten. Apparently, it was a prolonged amount of time spent at the mansion that inspired Bow to take her vacation to Poshley Heights.
The concept of a mansion haunted by ghosts and filled with puzzles has been used in other Mario games as well, most notably Super Mario World and Luigi's Mansion. Also, the Ghost House featured in Dance Dance Revolution: Mario Mix looks extremely similar to Boo's Mansion, including similar Boo portraits and chandeliers.
Mario is invited to the mansion at the beginning of Chapter 3 in Paper Mario. When he approaches the Forever Forest entrance in Toad Town, Bootler appears and tells him that Lady Bow has important news regarding the Star Spirits and wishes to see him. After Mario travels through Forever Forest and arrives at the mansion, he is told to see Lady Bow on the third floor. However, the stairs in the lobby only lead to the second floor. Mario must solve a series of tricks and puzzles to get to the third floor:
Once Mario reaches Lady Bow's room on the third floor, he will be greeted by Lady Bow and her servant, Bootler. They explain to Mario that the Boos are under attack from Tubba Blubba. Bow wants Mario to defeat Tubba Blubba for them, and promises to give him Skolar, the Star Spirit Mario is trying to save, as a reward. Lady Bow also says that Mario needs her help to defeat Tubba Blubba, and after an argument with Bootler, joins Mario's party. Bootler continues to worry about Lady Bow's safety and remains waiting for her return in the third-floor room. The two then set off for Tubba Blubba's Castle.
It is revealed that Lady Bow has set the puzzles to test whether Mario could live up to his reputation. She has also ordered that Igor, the Boo merchant in the basement, not sell any item to Mario. After Lady Bow joins Mario's party, Igor's shop will be open for Mario. Franky also appears in the lobby, telling Mario that he can use the shop before setting off to fight Tubba Blubba. The rest of Chapter 3 takes place in the area beyond the back gate of Boo's Mansion. Upon the liberation of the Boos, the background music in Boo's Mansion is replaced with a cheerful tune. Lady Bow decides to stay with Mario as well as handing Skolar over as promised. At the end of the game, Lady Bow returns to Boo's Mansion after her adventure with Mario, and receives an invitation letter to Princess Peach's party.
Boos in the mansion are crazy for Lady Bow. They would even scribble on the Toad Town notice board to confess their love for Bow as well as coming to the party at Peach's Castle just to see Bow in her finery. At one point, the Boos in Gusty Gulch write an admiration letter to Bow, greeting "everyone at Boo's Mansion".
One of Koopa Koot's sidequests and Parakarry's letter delivery sidequest involve interacting with Franky in the mansion. A pipe in Toad Town Tunnels, if unlocked, will serve as a faster way to go back to Boo's Mansion, as well as the areas beyond it.
Outside and the lobby
Boo's Mansion is located at a branch in the northwest of Forever Forest. It is a big, haunted house with many windows. According to a Boo, the mansion is passed down through the years by Lady Bow's ancestors.
The clearing in front of the mansion connects to Forever Forest via the fence and Gusty Gulch via the back gate. The latter is open after Lady Bow joins Mario's party. In the clearing, there is a ? Block containing a Volt Shroom and a bush growing Strange Leaves. There is also a pipe from Toad Town Tunnels, which can be unlocked later in the game. Finally, by the front side of the mansion are a Save Block and a Heart Block.Inside the mansion, the lobby is a big room that spans three floors, with doors to other rooms in the north. There is a sofa that shoots Mario to the chandelier. An underground Star Piece can be found near the sofa. However, there are only stairs up to the second-floor corridor, at the end of which is an empty frame. According to the frame, Mario must find whatever is missing in it to get to the third floor. It also mentions that this is a test from Lady Bow.
The east room on the second floor is almost empty, with three cabinets by the west wall. Mario must check the middle one, and play the guess-who-holds-it game with the Boos that come out. Once he picks the correct Boo, they will give him the Record. The other cabinets are traps. There is also an underground Star Piece at the center of the room.The west room on the second floor contains a phonograph and a treasure chest. A Boo is told to guard the treasure chest by Lady Bow. By playing the Record with the phonograph at the right pace, Mario is able to lure the Boo away and get the Weight inside the treasure chest. The Boo then disappears. The room also has a table and some chairs.
First floor and basement
The west room on the first floor is blocked by a glass case, which can be moved by attaching the Weight to the chandelier in the lobby. The treasure chest in the room is a trap. Going down the stairs by the left wall leads to a basement room with a clock and an underground Star Piece. To the right of the basement entrance is a library. To the south is a pair of storage rooms.
The first storage room has some crates on the ground, one of which contains a Super Shroom. There is a one-way door to the right, leading to the second storage room. The second storage room has a big treasure chest containing the Super Boots. Mario must play the same game with the Boos that come out of the chest to get the boots. Once he gets them, the Boos disappear, and another Boo appears and ready to inform Mario how he can use the boots to get the underground Star Piece in front of him. There are also crates containing a glass of Maple Syrup. To exit the room, Mario must break the wooden plate on the ground with the Super Boots to fall to the area even lower. In this lower area is Boo's Shop run by Igor. The shop remains closed for Mario until Lady Bow joins his party. There are also switches, pressing which will reveal the stairs that lead to the first storage room. This gives Mario a way to go back.Back to the lobby, the east room on the first floor has a vase containing an 8-bit easter egg as well as several crates where Apples can be found. By breaking the wooden floor on the ground with the Super Boots, Mario is able to land on the bookshelves in the library room mentioned earlier. On top of the bookshelves is the Boo's Portrait. Mario can also jump from on the bookshelves to the stacked crates nearby and break them, where he can find a Star Piece.
Lady Bow's room
The big, royal-looking room on the third floor is where Lady Bow and Bootler live, and where the Star Spirit Skolar is temporarily imprisoned. After Mario solves the puzzles and gets there, he will be greeted by the two. Lady Bow wants Mario to defeat Tubba Blubba and promises to free Skolar if he does so. She also says that Mario needs her help and joins Mario's party. Bootler intends to follow and protect Bow, but Bow insists that he waits here for her return, which he does. Mario and Lady Bow then leave Boo's Mansion and set off for Tubba Blubba's Castle.After Tubba Blubba is defeated near Windy Mill, Bootler goes there and hands Skolar over to Mario. But in other times, Bootler is seen in the room, worrying about Lady Bow's safety and waiting for her return. The room is seen again at the end of the game, this time with Bootler giving Lady Bow an invitation letter to the party at Peach's Castle.
