Black Fungus

The Black Fungus is a Heartless from Kingdom Hearts. Unlike the other Mushroom Heartless, it is very aggressive. It can turn into stone to defend itself and release poisonous gases, making it very hard to defeat. If you finish 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.
