The Poltergust 3000
I made up that name. I wanted it to be "The Boover 3000" but legal wouldn't clear it. Nintendo Power writers often helped The Treehouse (Nintendo's localization group) and Nintendo's marketing group with other stuff, like brainstorming names for in-game items, titles, box copy, tag lines, press releases and the like. That is how I ended up naming Luigi's vacuum weapon The Poltergust 3000.
