Luigi goes on an adventure around the world at the same time as the player, offering general information as well as clues for upcoming bosses. Once Smithy is defeated, he can be found in Mario's Pad and has his own line of quests for the player to complete.
Once all three Anti Guys have been defeated, Luigi will give the player his Luigi Hammer. Doing so causes General Guy to appear when trying to leave, but defeat allows the player to leave and prepare for the fight.
Quests[]
With the exception of General Guy and the Gold Blaster, these quests can be done in any order, although Luigi only gives a hint for the recommended one.
