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. Even-numbered Mushrooms drop numerous new weapons for Donald, while odd-numbered Mushrooms drop numerous new weapons for Goofy. You cannot even damage some of them unless you reach a certain level or certain abilities are equipped.

After beating the game, only twelve are accessible; the thirteenth Mushroom must be found after beating the other twelve. Once you find the thirteenth Mushroom, you get the Winner's Proof Keyblade.

Finding The Mushrooms

  • No. 2: is in Christmas Town. You must dodge or block its projectiles until your score reaches 85.
  • No. 3: is in Beast's Castle, where you fought Xaldin. You must have defeated Xaldin to reach it. You must collect 450 of the prizes it drops before time runs out.
  • No. 4: is in the Land of Dragons, outside the Palace. You must have defeated Shan-Yu to reach No. 4. You must hit 85 of the clones without getting hit once.
  • No. 5: is in the Cave of Wonders. This is probably the easiest one to beat. You must defeat it in 10 seconds, although its health automatically regenerates very quickly.
  • No. 6: is in the Underworld, where you fought Demyx. You must defeat all of the clones within 45 seconds. The clones appear in groups of 6.
  • No. 7: is in Twilight Town. You must defeat it in 10 seconds. However, coming in contact with the Mushroom will send a character flying.
  • No. 8: is in Twilight Town, outside Yen Sid's Tower. Many say that this is the hardest challenge: bouncing the mushrooms around like a ping-pong ball 85 times.
  • No. 9: is in Radiant Garden, where you fought Demyx. you must hit it 75 times without letting it stop spinning.
  • No. 11: is in Timeless River. You must deplete the hit counter in 19 seconds.
  • No. 12: is in Twilight Town, outside the Old Mansion. You must defeat all of the clones before time runs out. However, unlike No. 6, they appear by themselves.
  • No. 13: is in Radiant Garden, where you fought the 1000 Heartless. You must have beaten all of the other Mushrooms to reach the last Mushroom Heartless. You also gain a crown.

Trivia

  • All of the Mushrooms (with the exception of No. XIII) require minigames to be completed.
  • All of the Mushrooms have similar traits to the members of Organization XIII. For example, No. 7 can go "berserk", similar to Saix, while No. 11 has the same hit counter feature as Marluxia.
  • Wisdom Form is very useful for some of the minigames, such as No. 1 and No. 4. The minigames were likely engineered so that Wisdom Form would be made much more useful than in the original Kingdom Hearts II.
  • Before all of the Jiminy Objectives are completed, the Mushrooms (with the exception of No. 13) appear at the Great Maw, but warp away after about 2 seconds.
