Gooigi is a Luigi made of goo, he was made by E gad to be temporary partner to Luigi. He looks like Luigi but slimy and all green, he doesn't talk much but is very expressive, he has the poltergeist 9000 (Which is a vacuum that can suck of small stuff and ghost). He's very weak to water and need to be careful of it, he hates king boo and dry Bowser, he thinks that he's brothers to metal Mario but metal Mario treats him more as a friend, he is a good guy, Can regenerate small injury's, very nice
