Altering Mansion

There is a strange, abandoned mansion in Jenta made entirely out of brick. It's slowly crumbling down, so brick throwers generally get the fallen bricks to throw at people. However, wild Pokemon also inhabit these almost-ruins...but they change, as well. Check back frequently to see if a Pokemon you like is in here.

There are two locked areas in the mansion as well, the North Tower and the South Basement filled rare and valuable things. But can you guess the password?
