Fungi Light

The Fungi Light is a unique type of lamp seen on Mushroom World. Only two are known to exist, and both appeared in Super Mario RPG: Legend of the Seven Stars. One is actually owned by Mario, and can be found in his home. If Mario ever needs to rest, he should return to his 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 a costly inn). Ironically, the other Fungi Light is located at the most expensive inn in the game, the suite in Marrymore. Of course, turning off the light and taking a rest will recover all of the plumber's party's HP and FP. However, use of this lamp will cost two hundred coins, and an additional one hundred coins with each subsequent night stayed in the suite.

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