Stupid Luigi is a really bad bowler that regularly gets a point total of -100,000,000,000,000. He is really stupid and likes Luigi even though he doesn't know who he is. He thinks he likes pickles though he hates them as much as his dog does. His only appearance in a shame is in Mario Party 364 where he says:"Bye-bye, Luigi, I really don't like you." when Mario loses. His favotite toy is his mini-coockoo-clock which his mother smashed 7 years ago. He thinks his IQ is 450, but its actually 4.50. He is 3 years old, weighs 230 lbs., and is 7'13". His brother is named Popso-Lopso-Mopso.
How do we know all this if he is only a cameo? He is an actual living kid who lives three houses down your street. How do we know this? Were watching you!
