Princess Peach's Castle/Castle Grounds

The Castle Grounds is the outer portion of Princess Peach's Castle, where Mario first starts. It contains the entrance to the castle, the cannon to the roof where Yoshi resides, and Vanish Cap under the Moat.

The Castle grounds normally have a large, flooded moat, however, Mario can drain the water by ground-pounding the pillars in the Castle Basement. This will allow access to Vanish Cap Under the Moat and open a door directly into the Castle Basement from the Castle Grounds.
