Mushroom XIII

The Organization XIII Mushrooms are thirteen mushrooms that are dressed like the thirteen members of Organization XIII. In Kingdom Hearts II: Final Mix, they are located in numerous worlds. Each Mushroom has its own game that also has a Jiminy Memo objective to it. Odd-numbered Mushrooms drop numerous new weapons for Goofy. You cannot even damage some of them until you reach a certain level.
