Confront the Source

A-Boss: Confront the Source is the sixth and a boss mission in the Gloomy Manor from Luigi's Mansion: Dark Moon. In this mission, Luigi fights the Grouchy Possessor, who possesses a large spider.

Overview
Unlike all other missions, Luigi starts in the Lobby instead of the Entrance. In this room, he should investigate the elevator, which takes him into the Cellar. When Luigi arrives in the Cellar, he should go down the stairs, which suddenly slide him into the floor. Luigi should then attempt to suck up the web cord, in which the large spider is disturbed, thus starting the boss fight. Basically, all Luigi has to do in this fight is to use nearby fire, suits of armor attacking, and webs to reveal the Grouchy Possessor; once the Grouchy Possessor has been shocked three times, it is defeated and the mission is over.

Description

Trivia

 * The music that plays in the elevator is a cover-version of the pause screen music from Mario Strikers Charged.
