The Pokémon Mansion (Japanese: ポケモンやしきPokémon Mansion) is an area located on the northern half of Route 212. It is a big, old mansion owned by Mr. Backlot, the owner of Amity Square. The house is well-guarded outside. It is also the home of the famous Trophy Garden, which is located to the rear.
In the games
It has many rooms, with the most important of them being Mr. Backlot's office, which is where a Pokémon statue guarded by a policeman is located. However, the guard is on break from 2 A.M. until 6 A.M., leaving the player free to touch the statue (however, doing so will have no effect on the player or game whatsoever, even if they return after touching it). In addition to touching the statue, Pokémon Platinum players can record Manaphy's data (as a seen Pokémon) from the book lying on Mr. Backlot's desk. Other rooms in the mansion have beds, which can be used by the player to rest them self along with their Pokémon.
A butler and many maids are employed in the Mansion. In Pokémon Platinum, players may fight the maids in the 5-Maid Knockout Exact-Turn Attack Challenge, in which five maids must be beaten in a certain number of turns (no more, no less). The prize for winning the challenge is a duel with either Lady Celeste or Rich Boy Liam.
The western and eastern exits of the mansion are blocked by the maids. Neither of these doorways are functional, and only serve as decoration, as players with Action Replay have proven.
The Pokémon Mansion was featured in Hungry for the Good Life!. Mr. Backlot and his maid Monica also appeared in the episode. Monica first appeared before Ash and his friends trying to catch a Cleffa that escaped Mr. Backlot's mansion. Afterwards she took them back to the mansion to get out of a storm and meet Mr. Backlot. They also met all the Pokémon that Monica cared for. She made Poffins for them to eat. Dawn captured a Swinub and learned that the next Contest will be in Celestic Town.
