There are many hidden Luigis throughout the entire game. They reside within levels, in the overworld maps and even within minigames! While it is not yet clear whether or not they appear within every single level there are more hidden Luigis than you can shake a stick at. Please edit this section with more information as to whether or not a save file from Super Luigi U is needed to activate these hidden bonuses or if they are there for everyone to celebrate The Year Of Luigi one last time.
