After finding it, Mario and Goombella arrive in Petal Meadows, where they see Hooktail and her castle. To reach this place, they must find a pipe in Rogueport Sewers. Mario and Goombella show the updated map to Professor Frankly, who reveals that the first Crystal Star is in Petal Meadows. So, Mario holds the map before the Thousand-Year Door, revealing the location of the first Crystal Star. Said objects can be found by holding the Magical Map before the Thousand-Year Door, which is located in the town's sewers. At the professor's house, Frankly explains that the map is related to the legend of the treasure of the Thousand-Year Door, and that, to obtain the treasure, one must first open the door with the seven Crystal Stars. Then, Goombella suggests to go to Professor Frankly's house, to consult him and show him the map. As Goombella is also searching for the map's treasure, she decides to join Mario. After defeating the X-Naut general and escaping from the X-Nauts, Goombella introduces herself, and Mario explains his quest to her. Mario intervenes and Lord Crump tries to defeat him. Shortly after Mario reaches Rogueport, he finds Lord Crump attempting to interrogate Goombella about the Crystal Stars. Mario receives the letter with the map and decides to help her, and thus boards a ship to Rogueport. Soon after that, she is kidnapped by Sir Grodus. She sends this to Mario, along with a letter asking him to help her search for the map's treasure. The adventure begins when Princess Peach goes on a cruise to Rogueport where she meets a hooded woman, and buys a box which contains a map.
