The player can attack the crowd at this time. Occasionally, in battle, the crowd will throw things at Mario. In battle, Mario must keep his fans happy by executing action commands (hitting buttons at the right time during his attacks). Battles play out on a stage in front of an audience. Mario can jump, run, hammer, talk to people, etc. When Mario stands in front of the door, the map begins to show the locations of stars which open the door. The professor decides to take Mario to the thousand-year door. Goombella then takes Mario to her archeology professor. There he meets a female goomba named Goombella.
So Mario comes to place called Rogueport where Peach was last seen. Princess Peach finds a map and mails the map and a letter stating that Mario must come. It's not known what could be behind this door, but everyone has different theories. This is where the title 'the thousand-year door' comes from. Another city was built on top, and all that remains of the previous city is a door.
