The object is very simple. All you have to do is punch your opponents lights out before "Your" lights get punched out!!! Very simple, but also very satisfying!
New Luigi: Your main/final opponent.
Big Mac: You.
Glass Joe: A guy made entirely out of glass.
Cardboard Joe: A guy made entirely out of cardboard. (Brother of Glass Joe.)
King Hippo: King of the hippos.
King Blobby: A human blob.
Bear Hugger: Some fat dude who hugs bears.
Bald Bull: A bald bull.
Waldo: Retardedly easy guy.
The King: King of the kings. (is that possible?)
Bowser: HIM TOO?!?!?!? (looks like EVERYBODY we knows in this game!)
Evil Guy-The real final oppent. He eats New Luigi and tries to punch your brains out, DUH!
