Ideas of questionable quality

Ability to carry ghost critters on your shoulder, like how you can with a mentor mouse, + little cosmetic effects when doing so

For example, carrying a ghost butterfly on your shoulder will make your character sprite sparkly and shiny, or a roach ghost might slightly alter the color palette of (facial) hair and whatnot. Effects revert when the ghost critter is no longer on your shoulder.
