Black Fungus

The Black Fungus is an Emblem Heartless found in Kingdom Hearts, Kingdom Hearts: Chain of Memories, and Kingdom Hearts Re:coded.

Design
A Black Fungus has a spherical, pitch black head with two glowing yellow, beady eyes. It wears a round, purple cap on its head that sports two black, angular spirals on its front. It also seems to wear a navy blue smock that completely covers its legs and thin, fingerless arms. Its Heartless emblem is present on the front of this smock.

The Black Fungus's name references its dark coloration, as well as , a biological kingdom that contains organisms such as mushrooms and truffles.

Strategy
Unlike the other Mushroom Heartless, it is very aggressive. It can become invulnerable for a short time to defend itself and release poisonous gases, making it very hard to defeat. If Sora finishes them off with a critical hit at the end of a combo, they may either drop a Mystery Goo (100%), or a Mystery Mold (10%). It is possible for them to drop both, and upon being finished with a Critical Hit, they drop around 20 to 100 Munny.

If having trouble finding Mystery Mold after defeating a Black Fungus, use Trinity Limit. If Sora doesn't have Trinity Limit yet, use Gravity, as it is usually a one-hit knockout. Since the Black Fungus drop Mystery Mold after critical hits, make sure to remove all Combo Pluses before fighting them to shorten the length of the combo.

In Kingdom Hearts: Chain of Memories and Kingdom Hearts Re:Chain of Memories, the cards it uses are numbered 7, so be sure to break them accordingly. Defeating Black Fungi usually yields a Calm Bounty card, so exhausting Black Room cards is a rather easy way to stock up on Calm Bounty cards.
