Slim Bankshot

Slim Bankshot, the Lonely Poolshark (Japanese: ボール・ロング Ball Long), is a portrait ghost that loves to shoot billiards. He was a legend in the competitive pool circuit, despite the fact that he never played a living soul. Slim spends his afterlife practicing alone in the Billiards Room of Luigi's Mansion. Although Slim Bankshot is a portrait ghost, Luigi does not need to capture Slim to help save his brother Mario from King Boo. However, if he decided to catch the spirit, Luigi will be rewarded with the ghost's great treasure.

When Luigi first encounters Slim Bankshot, the portrait ghost is playing 3-Ball, shooting billiard balls with his cue stick. In fact, Slim hits the balls so hard they go flying off the table and bounce around the room (causing five HP of damage if they hit Luigi). Each time they are hit, he goes around the pool table once before hitting the balls again. To make Bankshot vulnerable, Luigi has to suck up one of the flying billiard balls with the Poltergust 3000. The ball will then get stuck at the end of the vacuum, allowing Luigi to shoot the ball like a projectile at Slim Bankshot. The billiard balls that Slim shoots fly around the room leaving red streaks behind them. The ball that Luigi shoots will leave a blue streak. After being hit three times, Slim will become limp and vulnerable and Luigi can capture the ghost with his Poltergust. If Bankshot manages to break free from Luigi's hold, the spirit will return to shooting pool. As such, Luigi has to hit Slim with another billiard ball to make the portrait ghost vulnerable again.

After combating Slim's medium pull, Luigi captures the ghost and lights up the Billiards Room. After Bankshot's treasure chest appears, Luigi opens the box and receives a Silver Diamond and two Gold Bars, along with other minor treasures. With another portrait ghost eliminated, Luigi continues the search for his brother.

A black-and-white picture of a person similar in appearance to Slim Bankshot can be found on the north wall of the Billiards Room, possibly depicting him when he was alive.

Trivia

 * In billiards, a "bankshot" (or "bank shot") is one where the player hits the cue ball against a railing before striking another ball into a pocket.
 * Occasionally, a billiard ball that Slim fires will bounce off of a wall and hit Slim while he travels around the table, effectively meaning that he hit himself. It is still advised to actively shoot the balls at him though, as that only happens rarely.
 * In the Courtyard, there is a statue of Slim kneeling down in a proposal-like fashion.
 * As the balls hit Slim, he appears more and more fatigued when attempting to make a shot.
