"Mario! Mario! MARIOOOOO!!! D:<"
– Luigi Doll
Luigi Doll is a doll version of Luigi. He lives in your nightmares and subconscious.
He is a friend of Tails Doll.
Similar to Weegee, Luigi Doll is a creepy doll that he will stare at someone else. He can glow in the dark and say "Mario!" God, it's annoying, believe me.
