The Money Bin is a large building that houses a large sum of Scrooge McDuck's fortune and Scrooge's main office for McDuck Enterprises. It is separate from his home, and is down the street from his mansion. It is in Duckburg, on the bay.
Gearloose Labs is the laboratory from which Gyro Gearloose, Fenton Crackshell-Cabrera, Lil Bulb, and Manny work. It is located on the Money Bin's basement floor, underwater. Because of this the lab floods whenever the windows break.
