You can use the Home Economics Classroom Key to enter or leave the room.
This place is a room to do cooking class. So that place has items needed to cook. Such as a Stove, plate, ventilation etc...
After defeating the Machine Room Ghost in the Workshop, the players can only go out through the hole that is connected to this place.
Unlike the original, the player couldn't enter the room until Hell mode was added later in the game.
- In the original, players must select the Home Economics Classroom Key and use the keyhole in order to leave the room.
