The starting planet (or you can call it the Mansion Planet) is a large, dark tower. The inside is a large maze. To get to the top, Mario/Luigi must use Yoshi and make him consume Blimp Fruits, allowing him to slowly fly upwards. However, they must avoid the Mines and other enemies such as Pumpkinhead Goombas and Paragoombas inside as well. A Comet Medal is found in this planet. At the top of the planet is a Launch Star, which will blast Mario/Luigi to the Maze Walkway Planet.
