Steven Universe - It was a very good episode but logically he seriously could've done that; plot over

That's exactly what I thought. Like, at most Greg would need like, a one story, 2 bedroom house. Hell if anything he just hire a construction company. Build a shack nearby his car wash. Solid wood or concrete. Foundate it to the ground decently. Few yards by few yards. Or 10 by 10. Get a lantern or a good lamp maybe. An actual bed with a mattress. Get a nice shelf in there, put up your photos and memorabilia.

Patrick Star lives better than you Greg. And his furniture is sand now. It used to be real furniture in a small divet, but now he's decked out. C'mon man.

If there's any misinformation, Greg still has money left.
