Lavenderjuice's Ultimate Luigi Edits Pack, a bundle containing a good chunk of Warner Luigi edits
this is mainly a huge pack of Warner Luigi edits, so unfortunately no ShinSamus Luigi or any other
version of Luigi you were expecting (poc-luigi, SNS's version, etc).
also, there's 15 chars (12 Luigi edits) on each folder in the pack.
