The '''Mushroom XIII''' are a group of [[Emblem Heartless]] that appears in ''[[Kingdom Hearts II Final Mix]]''. All thirteen Heartless that make up the group wear [[black coat]]s and, like other Mushroom Heartless, must be satisfied in a special mini-game in order to be defeated. As [[Sora]] completes the challenges issued by the Mushroom XIII, his results are recorded in [[Jiminy's Journal]].
{{TOCleft}}
{{-}}

==Prizes==
When defeated, each of the Mushroom XIII drops [[Tranquility]] materials. The six even-numbered Mushroom Heartless drop Shields for [[Goofy]] to wield, while six of the seven odd-numbered Mushroom Heartless drop Staves that can be wielded by [[Donald Duck]]. Fulfilling the highest requirements for odd-numbered and even-numbered Mushroom Heartless unlocks the [[Premium Mushroom]] and [[Ultimate Mushroom]], respectively. When the thirteenth Heartless has been satisfied, Sora obtains the [[Proof of Peace]] and the [[Winner's Proof]] Keyblade.

==Design==
[[File:Mushroom XIII Sprite KHIIFM.png|left]]
For the most part, each Mushroom is physically identical. The Mushroom Heartless all sport the same spherical, pitch-black heads and glowing, yellow eyes. They all wear black coats reminiscent of those worn by the members of Organization XIII; these coats are adorned with similar zippers, pull-strings, and hoods, although the hoods resemble mushroom caps and have twin angular, black spirals decorating them. The Heartless emblem appears on the front of each of the Mushroom XIII.

Only two differences exist between the Mushroom XIII: the Heartless are all different sizes, and they all sport different numbers on their backs. The Roman numerals on the backs of the Mushroom XIII are silver and range from I to XIII. These numbers denote the rank of a particular Mushroom Heartless. The sizes of the Mushroom XIII vary greatly; No. 5 is the largest Mushroom Heartless, while No. 8 is the smallest, being roughly half as tall as Sora.

The Mushroom XIII's collective name refers to its members' mushroom-like shape and resemblance to Organization XIII.

'''No. 1''' appears at [[Memory's Skyscraper]] after [[Xemnas]] is defeated. Sora has 30 seconds to hit it as many times as he can.

No. 1 will continuously attempt to use [[Reversal]] to get behind Sora, but this will allow Sora to use his own "Reversal" and "[[Quick Slide]]" reaction commands. Once both commands expire, No. 1 will dash at Sora, knocking him back. If Sora can get behind the Mushroom with either Reversal or Quick Slide, the Mushroom will become confused and drop its guard. The key to defeating it is to wait past Reversal for the more effective Quick Slide, which instantly makes the Mushroom open to damage—it is also possible to make the Mushroom vulnerable using Reversal, but requires at least two uses and often sends Sora in the wrong direction, negating its effect. The window on Quick Slide is very small, and Sora can only deal nine hits at a time, so it is recommended to use Wisdom Form or Final Form in order to deal them as quickly as possible.

Like Xemnas, this Heartless has the "Reversal" reaction, and like the Memory's Contortion battle, the key to dealing damage and avoiding being stunned is to use good timing with the reactions instead of mashing them as soon as possible. Its large size is a reference to Xemnas's role as the Superior of Organization XIII, and its location is a reference to the first battleground with Xemnas.

'''No. 2''' appears at [[Christmas Tree Plaza]] after [[the Experiment]] is defeated. Sora must avoid being hit by its projectile attacks.

No. 2 will circle Sora, strafing him with magic projectiles.{{?}}<!--expand discussion of its behavior--> The key to defeating it is to parry or dodge its attacks using [[Auto Assault]], [[Guard]], [[Aerial Dodge]], or [[Reflect]], making sure to face the Mushroom as much as possible.{{?}}<!--Ultimania recommends Combo Plus? Can anyone figure out why?--> [[Stitch]] is a helpful supplement to these, as he will restore MP and occasionally deflect projectiles. <!--When the player sees the mushroom shoot a bunch of projectiles at Sora in a circular shape, using Reflega will deflect the projectiles back to hit the mushroom, which increases the score more than dodging them.-->

Like Xigbar, it shoots projectiles that must be deflected.

'''No. 3''' appears at the {{c|Bridge|bc}} after [[Xaldin]] is defeated. Sora has a set amount of time{{?}}<!--specify--> to collect as many dropped prizes{{?}}<!--specify; 500 total(?)--> as possible.

No. 3 will run back and forth across the Bridge, slowly at first but gradually picking up speed. The key to defeating it is to equip as many [[Draw]] abilities as possible while using [[Glide]] or [[Quick Run]], supplemented by [[Final Form]] and [[Wisdom Form]] if desired, to stay close to the Mushroom. The dropped prizes{{?}} quickly disappear, and at a regular pace{{?}}<!--8 times(?)--> the Mushroom will drop larger clumps of prizes{{?}}.

Like Xaldin, it flies back and forth across the Bridge, and the prizes it drops resemble the spheres{{?}} on which Sora uses [[Learn]] during the Xaldin battle.{{?}}. Its location is a reference to the battleground with Xaldin.

{{Q|Press {{button|t}} to begin the duel! Defeat the enemy without getting caught!|Information}}
'''No. 4''' is in [[The Land of Dragons]] - Palace Gate. [[Shan-Yu]] must have been defeated to reach No. 4. Sora must hit 85 clones without getting hit. 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 Sora should keep a distance and use Thundaga to destroy 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 Sora can hit several clones at once without being hit. Wisdom Form's Combo Finisher often slows Sora down towards the end of it, so equipping Berserk Charge and emptying the [[MP Gauge]] for a never-ending combo is also a good idea, in the event your MP replenishes, use Blizzard or Thunder to quickly drain it again while still damaging the clones.

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

}}
{{Q|Press {{button|t}} to begin the duel! Attack continuously, and don't let him heal!|Information}}
'''No. 5''' is in the [[Cave of Wonders]] - Treasure Room. Sora must defeat it in 10 seconds, without letting its health regenerate. 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, equipped with Fire Boost and the 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===

}}
{{Q|Press {{button|t}} to begin the duel! Quickly defeat the enemies that appear!|Information}}
'''No. 6''' is in the [[Underworld]] Caverns: Atrium, where [[Demyx]] was first fought. Sora must defeat all of the clones within 45 seconds. The clones appear in groups of six, though the initial one must be attacked first. Notable patterns are appearing in circles, which make Firaga most useful, appearing in straight lines, making Blizzaga most useful, and appearing in vertical lines, making Thundaga most useful. The clones are very weak, so it is recommended to take advantage of Final Form, which not only allows powerful magic but also makes the Keyblades strike adjacent foes when Gliding or jumping, making it much easier to defeat the mushrooms in more difficult formations.

The clones are reminiscent of the boss battle against [[Zexion]] in the "Reverse/Rebirth" mode of ''Kingdom Hearts Re:Chain of Memories'', and the various formations may recall those of the various book clones in the Absent Silhouette fight.

}}
{{Q|Press {{button|t}} to begin the duel! Defeat the enemy while avoiding its attacks!|Information}}
'''No. 7''' is in [[Twilight Town]] - Tunnelway. Sora must defeat it in 10 seconds. However, coming in contact with the Mushroom will send him flying.

The key to defeating No. 7 is by using long-range attacks. Wisdom Form works well, though Sora 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. Using Donald's Fantasia or Flare Force allows for easy damage while also keeping Sora invincible, allowing him to attack in conjunction. However, the most effective method is to use Reflega while in Final Form, although Thundaga can also work.

The Mushroom sending Sora flying on contact is similar to the attacks of [[Saïx]] while in his Berserk state.

}}
{{Q|Press {{button|t}} to begin the duel! Once you pull it out, don't let it touch the ground!|Information}}
'''No. 8''' is in Twilight Town, outside the [[Mysterious Tower]]. The objective is to bounce the mushroom around like a ping-pong ball 85 times, similar to the [[Rare Truffle]] in the first game.

One way to defeat the challenge is to equip Berserk Charge and remove all [[MP Haste]]-type abilities, use Cure to empty the MP Gauge, then repeatedly hit the Heartless with Horizontal Slash or Master Form attacks<!--is there an ability for the basic slash?-->. If MP refills before the desired hit count has been reached, use Trinity Limit to deal the final few hits. The [[Fenrir]] Keyblade is the best for this fight, as it has the longest reach of any Keyblade in the game.

An alternate way of doing this is to enter Wisdom Form, and to use the Shoot command repeatedly until its finisher is reached, then use the Thundaga finisher once or twice to complete each combo. At least two finishers per combo are required for this so equip [[Finishing Plus]] and Rumbling Rose if acquired. Equipping [[Magic Lock-On]] makes this easier due to it automatically locking on to the Mushroom and increasing Thundaga's range.

It is similar to the Overtake Reaction Command in [[Axel]]'s boss fight on the 6th Day of the Prologue. Its small size could be a reference to Axel's waning loyalty to the group. It must also be pulled out of the ground to attack it, similar to the Assassin Nobodies.

}}
{{Q|Press {{button|t}} to begin the duel! Attack and keep the enemy spinning!|Information}}
'''No. 9''' is in [[Radiant Garden]] - Castle Gate, 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. It is also the location where the Melodious Nocturne met his end.

}}
{{Q|Press {{button|t}} to begin the duel! Find and attack her real form!|Information}}
'''No. 10''' is in [[Port Royal]] - [[Isla de Muerta: Moonlight Nook]] during the second visit. Sora must defeat the real Mushroom in 55 seconds as it shuffles itself amongst four clones. The only notable strategy is to stand back to where all clones are visible and then repeatedly pause the game to make it easier to keep track of the real one, and then use Final Form to deal as many hits as possible to the real form; after each consecutive correct guess, more time will be added before it shuffles itself again, but after each incorrect guess, the time to hit it will restart.

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

The fighting style of No. 10 is identical to that of the [[Black Ballade]] in ''[[Kingdom Hearts Final Mix]]'', where hitting the wrong one would result in Sora taking damage.

{{Q|Press {{button|t}} to begin the duel! Keep attacking until the number counts down to 0!|Information}}
'''No. 11''' is in [[Timeless River]] - Waterway. Sora must deplete the hit counter above its head in 19 seconds. The best way to defeat it is by using Wisdom Form with Rumbling Rose and all Finishing Plus abilities to take advantage of the Wisdom Form's burst-fire finishing move. Sora can also use Wisdom Form combined with Berserk Charge, making sure to empty the MP Gauge immediately before starting the battle in order to use Berserk as soon as possible. Alternatively Sora can un-equip all of his Combo Plus and Air Combo Plus abilities and equip Fenrir and Negative Combo so that Sora's Wisdom Form fires continuous burst-fire finishing moves.

The hit counter resembles the one [[Marluxia]] uses against Sora in his Absent Silhouette battle.

{{Q|Press {{button|t}} to begin the duel! Defeat the enemies that appear before you!|Information}}
'''No. 12''' is in [[Twilight Town]] - The Old Mansion. Sora must defeat 40 or more 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; normal attacks or finisher strings are both capable of completing the challenge, either using Berserk Charge or the Fatal Crest, or unequipping all Combo Plus abilities, equipping Finishing Plus and Negative Combo, and using Fenrir to fire continuous finisher bursts. Proper control of the camera helps greatly in completing this challenge, as the clones can appear among and on top of the pillars on the mansion grounds where they may not seen easily and Wisdom Form's shots will not auto-aim toward them. Avoid locking onto the clones and sweep the camera around to keep more of the area in view and see where the clones are appearing, then move in to fire at them.

The clones' rapid appearance reference [[Larxene]]'s Absent Silhouette battle.
{{-}}

===No. 13===
'''No. 13''' is in Radiant Garden - Great Maw (where the 1000 Heartless battle took place). After beating the game, each time Sora enters the Great Maw, the other twelve Mushrooms will appear before him. A second later, all Mushrooms whose challenges he has yet to complete will vanish, while those remaining will jump for joy. If all twelve have been appeased, a beam of light will appear, and approaching it will give the Reaction Command "Look Up". Doing so will reveal No. 13, who descends from above directly before Sora. After the cutscene, the Reaction Command "Ready, Go!" appears. Activating the command will result in No. 13 giving Sora the Winner's Proof Keyblade and the Proof of Peace. After that, the thirteen mushrooms ascend into the sky together; while the other twelve are still available to be challenged, No. 13 will never appear again.

Its non-hostility compared to the other twelve references [[Roxas]] as being unusual compared to the rest of the Organization. Also, the way it appears is a possible reference to Roxas's element of light.
