Mushroom Course

The Mushroom Course is a golf course in Mario Golf: Advance Tour. It is unlocked by completing the other four courses' tournaments and is the last tourney to go through for both singles and doubles. Once the player has every trophy from Marion to Links, Princess Peach will send the player an invitation to compete in the Mushroom Kingdom. A glowing sphere will appear in the center of the Marion Clubhouse's foyer. Upon interacting with the sphere, Toad jumps out, asking the player if they wish to proceed to the Mushroom Kingdom. Princess Peach then begins the Mushroom Tourney. Mario then goes into the pipe first, and every one follows Mario to play the tourney.

The player can decline the start of the tourney and explore around the castle or go back to the Marion Clubhouse, though there are no side games in the Mushroom Kingdom.
