Maxwell

Maxwell is a character in EarthBound. He is an older, more experienced student at the Snow Wood Boarding House. When Jeff tries to open the lockers, he finds that they are locked, so Maxwell gives him a key. The key is busted however, so Maxwell gives him the Machine that Opens Doors Especially When You Have A Slightly Bad Key.

Jeff also calls Maxwell to save his game while he travels alone, instead of Ness's father.
