How to Unlock Luigi Bros.
This year, 2013, is Luigi's year. As a celebration, Nintendo offers a special episode in Super Mario 3D World for all Luigi fans. That is, to unlock a particular edition of the Mario Bros. original where all characters are Luigi.

How to unlock? First you need to buy a copy of New Super Luigi U and secure a save file on your Wii U console. This will automatically unlock Luigi Bros. Play it by clicking on the Luigi icon on the the leftside corner of the touch screen of your Gamepad.

The alternative and significantly more challenging way is to beat Worlds 1-8 in Super Mario 3D World - but this does mean you don't have to put your hand in your pocket for New Super Luigi U if you don't want it..

What are the Hidden Luigis for?
There are quite a number of 8-bit Luigis scattered throughout the whole Super Mario 3D World. You'll see them everywhere by using binoculars at some instances or while hitting blocks. (He even peers through the window of some Sprixie Stamp houses) They don't affect your game whatsoever. They're just there for show. You don't receive any reward or stars for finding them. In short, they don't matter they're just a nice novelty. It gives us a warm fuzzy feeling to know that 8 bit Luigi is with us in spirit.
