Yugi's workshop is a slightly sawdust-smelling shop classroom, with a couple long wooden work tables across the middle of the room and storage bins along the walls, under the windows. There's all kinds of tools to work on projects—from things like hammer and nails and paintbrushes up to and including things like soldering irons, wiring kits, and circular saws. Along the window, someone's also left a ham radio kit, but for some reason all the stations only play Japanese 80s music.
In the back of the classroom, one workbench has been pushed to the side to make room for a slightly dated-looking but comfortable couch, plus a curtained-off area with a cot, sink, eyewash station, and a medical kit in case anyone has a terrible jigsaw-related accident.
And of course, at the front of the room, there's a blackboard for drafting plans on! The whole thing is big enough to have a couple friends over to work on a big project together, too.
