Waiter

Waiter Ghosts are undead blue ghosts in the Dining Room that serve food to Mr. Luggs in Luigi's Mansion.

Strategy
When Luigi lights up the candles with his fire and then vacuum Mr. Luggs' food, two Waiters will bring food to him and will disappear. Then have only ten health and it makes them cancel the servings.

Luigi shouldn't vacuum it once he sees a banana peel as that damages him.

If there's a Gold Mouse when Luigi sees the Waiters, Luigi mst vacuum the mouse and then vacuum the waiters.

If a Speedy Spirit appears when there are Waiters, Luigi should vacuum the Speedy Spirit and then vacuum the Waiters.

Trivia
The Waiters will disappear after they're done serving to Mr. Luggs.
