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.

The resell value of an Arts is merely 250 munny.
The White Mushrooms make different movements to show what spell they want Sora to cast.
