Mushroom XIII

The Mushroom XIII are a group of thirteen Mushroom Heartless that wear Black Coats which appear in Kingdom Hearts II Final Mix. Like all Mushroom Heartless, they each require special treatment in order to be properly satisfied. The mini-games required to complete their challenges are recorded in Jiminy's Journal.

Once defeated, a Mushroom will drop one of the Tranquility materials, which are designed after the Mushroom XIII. In addition, the six even numbered Mushrooms will drop shields for Goofy, while the six odd numbered Mushrooms will drop staves for Donald Duck. Fulfilling the highest requirement for each Mushroom will also reward the player with the Premium Mushroom for the odd numbered Mushrooms and the Ultimate Mushroom for the even numbered Mushrooms. Unlike the others, the thirteenth Mushroom doesn't drop a shield or a staff, but the Winner's Proof Keyblade and a Proof of Peace.

Design
All of the Mushroom XIII Heartless share a common appearance. They all sport the same spherical, pitch-black heads and glowing eyes, and they all wear black coats reminiscent of those worn by Organization XIII. These coats are black and sport similar zippers, pull-strings, and hoods—the latter of which resembles a mushroom cap and has two angular, black spirals decorating it. The Heartless emblem is displayed on the front of all of their coats. The members of the Mushroom XIII only differ in two regards; the numbers on their backs and their size. Each Mushroom XIII member has a different silver Roman numeral from I to XIII on their backs, representing their rank. The members' sizes can vary greatly. No. V is the largest and is larger than Sora, while No. VIII is the smallest, and is roughly half of Sora's height.

The Mushroom XIII's collective name reflects their mushroom-like shape and their resemblance to Organization XIII.

No. 1

 * The strongest Heartless of the bunch. It moves quickly and deals precise attacks.


 * Attack it to earn points! As soon as it performs Reversal, perform your own Reversal to catch it off guard.

No. 1 appears at Memory's Skyscraper after Xemnas is defeated. In order to defeat it, Sora must hit it 70 times within 30 seconds. In order to get the Premium Mushroom, Sora must hit it 99 times.

Like Xemnas, this Heartless has the "Reversal" reaction, and its large size is a reference to Xemnas's role as the leader of Organization XIII. In addition, its location is a reference to the first fight against Xemnas, which takes place in Memory's Contortion. It is recommended to use Wisdom Form to defeat No. 1, since it has quick attacks, and Sora can land at least three hits with the Shoot function. Final Form is very useful too. With one jump and an attack Sora can land 9 hits.

No. 2

 * A Heartless that attacks with a barrage of magic projectiles.


 * Avoid its attacks to earn points. Launch them back to earn even more points!

No. 2 is in Christmas Town, where The Experiment is fought. Sora must dodge or block its projectiles until the score reaches 80. Final Form is highly useful for No. 2, since nearly 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

 * A clumsy Heartless that drops valuable items.


 * Chase it to collect what it's lost! At times it's known to drop a whole trove of goodies.

No. 3 is in Beast's Castle - Bridge. Sora must have defeated Xaldin to reach it. Sora must collect 450 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



 * A Heartless that loves a good game of tag—and loves being "it."


 * It summons allies while chasing its enemies; don't let their sheer number overwhelm you. Defeat them one at a time for victory.

No. 4 is in The Land of Dragons - Palace Gate. Shan-Yu must have been defeated to reach No. 4. Sora must hit 85 of the clones without getting hit once. A recommended strategy is to hit the first batch of clones normally, and then use Final Form to fly around and ram into the clones with the spinning Keyblades or using Thundaga with the Photon Debugger equipped. The Form may run out near the end of the duel, when the clones are stronger, so the player should keep a distance and use Thundaga to kill the last few clones and reach 85. An easier alternative is to use the Wisdom Form, and move in a circular motion across the square while shooting, this way you can hit several clones at once without being hit.

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



 * A tough Heartless that regenerates HP as it sleeps.


 * Defeat it by hitting it fast and hard to drain its HP.

No. 5 is in the Cave of Wonders - Treasure Room. Many would say that this is probably the easiest one to beat. Sora must defeat it in 10 seconds, although its health regenerates 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 the Mushroom's health. Another strategy is to use Final Form, equip Fire Boost and Bond of Flame, and keep attacking with Firaga.

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's size compared to the other Organization members.

No. 6



 * A Heartless that creates copies of itself, and attacks using various formations.


 * Figure out which formation it's using and quickly work out a plan of action!

No. 6 is in the Underworld Cavern - Atrium, where Demyx was fought. Sora 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

 * A dangerous Heartless with a violent streak.


 * If you get too close, it'll blast you away. Defeat it with long-range attack like magic.

No. 7 is in Twilight Town - Tunnelway. Sora must defeat it in 1 minute and 0.03 seconds. However, coming in contact with the Mushroom will send him 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, one can 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

 * A Heartless buried in the ground, waiting to be pulled out.


 * Once you pull it out, keep attacking until it's dead. Make sure you don't drop it!

No. 8 is in Twilight Town, outside the Mysterious 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 easier is to equip Berserk Combo, repeatedly press Thundaga until MP runs out, then keep hitting it over and over. When MP is refilled, repeatedly press 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 on the 6th Day of the Prologue.

No. 9

 * A Heartless that loves to dance. Hit it, and it won't stop spinning.


 * Attack quickly and repeatedly to keep it spinning out of control.

No. 9 is in Radiant Garden, where Demyx was fought. Sora must hit it 75 times without letting it stop spinning. This can be accomplished by attacking with the Fatal Crest Keyblade, Berserk Charge and Horizontal Slash equipped, a combination which can land up to 99 hits.

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

 * A Heartless that confuses its enemy by creating copies of itself.


 * Defeat it by finding and attacking its real form.

No. 10 is in Port Royal - Isla de Muerta during the second visit. Sora 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



 * A poor Heartless that's always being chased by a mysterious number.


 * Attacking it will reduce the number. Transform the number to 0 as quickly as possible!

No. 11 is in Timeless River - Waterway. Sora 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, combined with the Fenrir Keyblade, Negative Combo and taking off all Combo Plus abilities.

No. 12

 * A Heartless that warps to various areas on the map only to mock Sora.


 * Defeat it by locking on to it or using long-ranged attacks!

No. 12 is in Twilight Town - Old Mansion. Sora must defeat 40 clones before time runs out. However, unlike No. 6, they appear by themselves in rapid succession. A good way to defeat No. 12 is to use Wisdom Form, have Fatal Crest and Berserk Charge equipped and removing all Combo Plus abilities.

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

No. 13

 * A Heartless that appeared alongside an ethereal flash of light.


 * It bestowed upon Sora a treasure, as proof of defeating the rest of its kind.

No. 13 is in Radiant Garden - Great Maw (where the 1000 Heartless battle took place). Sora must have beaten all of the other Mushrooms to reach the last Mushroom Heartless. After its 'defeat', Sora gains a crown.

Its non-hostility compared to the other twelve references Roxas as being unusual compared to the rest of the Organization. Also, it appears 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 fought also reference where the Organization members were fought.
 * 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 the player enters 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 the player has completed the Jiminy Objectives for will stay and jump up and down.
