A Hospital is a unique type of room found in the Fortresses of both Kid Icarus and Kid Icarus: Of Myths and Monsters. Here, a Nurse will cure Pit of the Eggplant Curse, which causes Pit to endure being
a walking eggplant/aubergine who cannot fight and can only dodge. The curse is caused by touching an eggplant, tossed by an Eggplant Wizard.
PurposeIn Kid Icarus and Kid Icarus: Of Myths and Monsters, hospitals are found in fortresses where Eggplant Wizards are usually. The hospitals remain a completely silent room if Pit enters them with a normal status, and the nurse will only appear if Pit has been infected with the Eggplant Curse. Going to a hospital is the only way to get rid of the curse in these games. They are characterised by their grey background, which is usually out of a place, as well as the lack of enemies within them.
In Kid Icarus: Uprising, if Pit is turned into an eggplant then he won't need to go to a hospital. In fact, as Palutena rightfully says, there are no hospitals in this game. In fact, Palutena's power will remove the curse after a while. The eggplant curse sill prevents Pit from attacking in this time however.
