Fungi Light

The Fungi Light is a unique lamp owned by Mario and can be found in his home. If Mario ever needs to rest, he should return to Mario's Pad and turn off the Fungi Light. Not only will his HP and FP be totally recovered, Mario will also save some money (that would otherwise have been spent at an expensive inn).

Interestingly enough, in Monstro Town, Mario has to turn off an actual fungus before he can go to sleep.
