There is absolutely nothing behind that door.
you cant its impossible even with walk though anything cheats trust me sorry
idk if Pokemon xd is the same as diamond and pearl...if it is, go to mr. backlots garden after getting the pokedex
It's not possible. There's nothing behind the door, probably because the game designers wanted to make the mansion seem big without having to put in pointless rooms. Even if you were to hack it, there is nothing there. (The door to the very right with the maid in front, yes?)
Pokemon Diamond Pearl and Platinum are games in the Pokemon series. There is no secret store in Pokemon Pearl version.
There are 4 secret rooms like: top secret rooftop of coffee shop, secret backstage of pawforming arts center, secret lighthouse in sunshine shores cave, and treehouse in the entrance.
Afterlife Is One Of Them.
you can find them in mr backlots garden but it only has a 5% chance of holding it so just encounter a pikachu and pray it has the light ball
They're many secret rooms. There is the fire dojo, ninja dojo, secret angency room, and on celebrations their are secret rooms for members.
There are two secret rooms in club penguin, which one are you talking about?
For security.

On pearl the best secret probably would have to be is that You are the best trainer in your edition of Pokemon pearl. Nice job. Other than that masumada method of breeding Pokemon actually workd in pearl.
