Nabbit

According to the official site, the Nabbit was once an enemy of the Mario Bros., but is now on Luigi's side. He replaces Mario as another playable character in this game, but he's unique. As an ex-baddie, he is incapable of using powerups, but he is immune to any enemy's attacks, making him a very handy character for new players.[[File:Characters-nabbit.png|thumb|Nabbit:
