Rusty and his parents live in a simple house, designed much like a Pokemon trainer's house in the normal games. They have a sink, cabinet, trashcan and a TV as well as a large green rug in the center of the room with a table and chairs on it. They also have a red mat in front of the stairs.
Professor Tree's LabEdit
Professor Tree obtained a free lab when he decided to become a pokemon professor. It has all the basic things that a pokemon professor lab would, like a computer and table. The only differences is that it is messier and Professor Tree leaves drug related items laying around.
