Mr. Luggs

Mr. Luggs, the Glutton (Japanese: ター・ハン Tā Han), is a thirty-year-old portrait ghost that was released from his canvas prison by King Boo immediately prior to the events of Luigi's Mansion. Mr. Luggs is obese and as stated in his bio he even ate himself to death. However, even in death, Luggs is not satisfied, and spends his afterlife eating food in the Dining Room of Luigi's Mansion. Luigi can just walk by Mr. Luggs as he is eating and skip capturing him. If Luigi captures Luggs, Luigi is rewarded with money in a treasure chest.

If Luigi chooses to capture Mr. Luggs, he uses a Fire Elemental Ghost to light the candles on the table. After lighting all the candles, Mr. Luggs and his dinner becomes visible. To make Mr. Luggs vulnerable, Luigi needs to suck up Mr. Luggs's ghost gelatin with his Poltergust. Two Waiters attempt to resupply Mr. Luggs with more gelatin. Once they are sucked in, his meal can not be refilled. Mr. Luggs becomes enraged and attacks Luigi by spewing fifteen fireballs at him. Each fireball causes ten HP of damage and briefly lights Luigi on fire. However, Mr. Luggs quickly tires out, rendering him vulnerable to the Poltergust. If Luigi does not capture Mr. Luggs in time, Mr. Luggs gets back up and breathes five more fireballs before tiring again.

After capturing Mr. Luggs, the lights turn on in the Dining Room and a green treasure chest appears. The chest contains two Gold Bars, a Silver Diamond, and other smaller treasures.

Super Mario-Kun
Mr. Luggs also appears in volume 28 of Super Mario-Kun in the Luigi's Mansion arc and serves as a spoiled man. When Luigi and Toad encounter him, he orders them to give him food. Luigi does and almost gives Toad to him, but doesn't due to Toad dismaying. Luigi and Toad gives Mr. Luggs all the food they had, even Mario's hat, but Mr. Luggs still wasn't satisfied. Luigi gets annoyed and sucks Mr. Luggs up.
