UNRELATED - Theory: Looking at the Bronze Portrait Bogmire from Nintendo 3DS (and the looks), it looks like Bogmire IS in fact a minor ghost, but as a boss.

In fact, Bogmire is accordingly the product of the mansion's fear and despair. AND THAT'S NOT ALL!

See that? Looks like he is in fact a MINOR ghost that has became a big bad BOSS.
