Well it depends on which mystery dungeon game you're playing but in blue rescue team you first must defeat requasa and after the credits and you return to the rescue team base you'll hear about a cave in wishcash pond but it only allows one person to enter at a time. When you try to go to a dungeon your partner will stop you and ask if it would be better if you were to be your own team so you choose the answer coressponding to yes.
