The White Mushroom is an Emblem Heartless found in Kingdom Hearts and Kingdom Hearts Chain of Memories. It is one of the various Mushroom Heartless in the series, and rewards Sora for demonstrating his magical skills. It indicates the desired spell through charades, and each time Sora casts the correct spell, it will chime with joy and relinquish Tech Points. If Sora gets all three charades correct, it will reward Sora with restorative Orbs and synthesis materials related to the third spell's element, and if all three spells are the same, the White Mushroom will relinquish a rare Arts item or Premium Bonus. However, if Sora attacks the White Mushroom, casts the wrong spell, or takes too long, it will run away.
A White Mushroom has a spherical, pitch black head with two glowing yellow, beady eyes. It wears a round, red cap on its head that sports two black, angular spirals on its front. It also seems to wear an off-white smock that completely covers its legs and thin, fingerless arms. Its Heartless emblem is present on the front of this smock. Like other mushroom Heartless, the White Mushroom bears a resemblance to the mushrooms from Fantasia.
The White Mushroom's name references its light coloration, as well as mushrooms, which it resembles.
Kingdom Hearts Chain of Memories
The Arts items are obtained from White Mushrooms in Kingdom Hearts. They are proof that a White Mushroom acknowledged Sora as a master of a certain magic. In order to obtain them, Sora must use the same magic on a White Mushroom three times. If Sora shows all seven Arts to Merlin, he will give Goofy the Dream Shield. The resell value of an Arts is merely 250 munny (the resell value is 100 munny in Kingdom Hearts Final Mix.)
The White Mushrooms make different movements to show what spell they want Sora to cast.
The different "charades" and rewards are:
