Mushroom XIII

The Mushroom XIII (XIIIキノコ) are thirteen mushroom Heartless wearing Black Coats which appear in Kingdom Hearts II Final Mix. Like all Mushroom Heartless, they require special treatment in order to be properly defeated, and the mini-games required to deal with them are in fact recorded in Jiminy's Journal.

Each of them drops Tranquil Shards, Stones, Gems, and Crystals, and can drop unique weapons for Goofy and Donald - the six odd Mushrooms drop shields for Goofy, while the six even Mushrooms drop staves for Donald. Fulfilling the highest requirement for each Mushroom will also reward the player with the Premium Mushroom for the odd Mushrooms and the Limited Mushroom for the even Mushrooms. Unlike the others, the thirteenth Mushroom drops not a shield or a staff, but the Winner's Proof Keyblade and a Tranquil Proof.

No. 1

 * A Heartless that moves quickly and deals sharp attacks. It's the strongest of its group.


 * Hit it to get points! Time it so if it uses Reversal, you can use Reversal yourself to make a big opening!

The first mushroom appears at Memory's Skyscraper after Xemnas is defeated. In order to defeat it, you must hit it 70 times within 30 seconds. In order to get the Premium Mushroom, you must hit it 99 times.

Like Xemnas, this Heartless has the "Reversal" reaction, and its large size is a reference to Xemnas' role as the leader of Organization XIII. It is also fought in the same area as Xemnas. It is recommended to use Wisdom Form to defeat No.1, since it has quick attacks, and you can land at least three hits with the Shoot function.

No. 2

 * An aggressive Heartless that spreads shots of magic in succession.


 * Dodge its shots to earn points! Aim for even higher points by reflecting its shots!

No. 2: is in Christmas Town. You must dodge or block its projectiles until your score reaches 85. Final Form is highly useful for No. 2, since almost every action made in Final Form also guards Sora from external attacks, and the projectiles can be blocked.

Like Xigbar, it shoots projectiles that must be deflected.

No. 3
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.

The prizes may reference the opportunities for Sora to use the Learn and Jump commands from Xaldin in his boss fight. The location of the mini-game also references Xaldin.

No. 4
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.

Its cloning trait references Vexen's ability to create Replicas while avoiding being hit, which is reminiscent of the Chilly Academic's cowardice.

No. 5
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. For its fast attacks, Master Form is best used when defeating No. 5, as this gives it less recovery time. Limit Form's Zantetsuken ground combo finisher is also extremely helpful, as it can easily chop away an entire bar of Mushroom's health. Another strategy is to use Final Form, equip Fire Boost and Bond of Flame, and keep spamming Firaga. Another alternate strategy is Final Form again, but instead of Fire, use Reflega to achieve completion in about 8 seconds.

Its regenerating health is similar to the Power Meter of the Lexaeus Absent Silhouette battle. It is also the largest of the Mushrooms, narrowly exceeding No.1, also referencing Lexaeus' size compared to the other Organization members.

No. 6
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 six.

The clones are reminiscent of the boss battle against Zexion in the Reverse/Rebirth mode of Kingdom Hearts Re:Chain of Memories.

No. 7
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. This trait is similar to the Berserk state of Saïx.

The key to taking No. 7 out is by using long-range attacks. Wisdom Form works well, though the player will have to keep gliding away from No. 7. Alternatively, you may use Limit Form's Sonic Blade, Strike Raid and Ragnarok combos to keep it at bay. Final Form and Reflega is another extremely effective method.

No. 8
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, similar to the Rare Truffle in the first game. A way to make this easy is to equip Berserk Combo, spam Thundaga until MP runs out, then keep hitting it over and over. When MP is refilled, spam Thundaga again. Make sure to remove all MP Haste abilities.

It is similar to the Overtake/Clear Light Reaction Command in Axel's boss fight in the 6th Day of the Prologue.

No. 9
No. 9: is in Radiant Garden, where you fought Demyx. You must hit it 75 times without letting it stop spinning.

The Mushroom's spinning, or dancing, is a reference to Demyx's association with music and control of Dancer Nobodies. Also, it is the location where the Melodious Nocturne met his end.

No. 10
No. 10: is in Port Royal (Isla de Muerta) during the 2nd Time. You must defeat the real Mushroom in 55 seconds as it shuffles itself amongst four clones.

Finding the real one amongst fakes references Luxord's boss battle and the shuffling of cards.

The fighting style of No. 10 resembles that of the Black Ballade in Kingdom Hearts Final Mix, where hitting the wrong one would result in Sora taking damage.

No. 11
No. 11: is in Timeless River. You must deplete the hit counter above its head in 19 seconds.

The hit counter resembles the one Marluxia uses against Sora in his Absent Silhouette battle. The best way to defeat it is by using Wisdom Form.

No. 12
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 in rapid succession.

The clones' rapid appearance reference Larxene's Absent Silhouette battle.

No. 13

 * A mysterious Heartless that appeared with a divine light.


 * After seeing proof that the rest of its group had been defeated, it entrusted to Sora a treasure spoken of for generations.

No. 13: is in the Great Maw 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.

Its non-hostility compared to the other twelve references Roxas as being unusual compared to the rest of the Organization. Also, it comes down to you with a beam of light, a possible reference to Roxas's element of light.

Trivia

 * All of the Mushrooms have similar traits to the members of Organization XIII. Some of the locations where the Mushrooms are also reference the Organization.


 * Wisdom Form is very useful for some of the minigames, such as No. 1 and No. 4, and to a certain extent, No. 7. The minigames were likely engineered so that Wisdom Form would be made much more useful than in the original Kingdom Hearts II.


 * When you enter the Great Maw, all of the Mushrooms (save for No. 13) will appear. Then, after a short period of time, all of the Mushrooms will warp away; however, the ones you have completed the Jiminy Objectives for will stay and jump up and down.
