As Luigi fell asleep, he felt he was getting pulled into a strange world. He felt...strange. "Hello!" Luigi quickly turned around, to see a familiar jester. His fists tightened, "You! You did this to me!" Luigi charged towards Dimentio. The jester quickly floated up out of Luigi's grasp. "Hey, calm down Green Thunder, I'm here to help!" Luigi quickly snapped, "Don't call me that, get out! I don't want you here!" Dimentio giggled, "Well, okay. I was going to offer you a solution to your present problem, but since you're not interested...." Luigi's eyes softened. "W-what? What do you mean?"

 Dimentio smiled. This person was so easily persuaded. "Well, I've been trapped in this dimension. I'm calling it the dream world. It's rather boring, I've have nothing to do, but then I remembered you, old pal." Dimentio circled around Luigi. Luigi asked, "M-Me?" "Yes. I remembered how strong and powerful you were, even when you weren't acting as Mr. L, so I decided to check up on you, just to see what kind of adventures you were getting up to." Luigi looked down as Dimentio continued, "But then, I saw that your brother wasn't even bringing you along on all these adventures. I was quite upset, someone as strong as you shouldn't be watching from the sidelines." Luigi's expression slightly shifted to anger. "Yeah, well sorry to disappoint you."

Dimentio looked at the green plumber. His smile grew. "Now, why won't your brother take you on his adventures? Have you done something wrong?" Luigi looked up at him. "Yes. I allowed myself to become that...thing. I allowed myself to be the villain. I-" Dimentio interrupted. "Shh, shh. I see your problem. He's scared of how powerful you are when you allow yourself to become Mr. L?" Luigi turned away. "Yes."

"Dimentio began dancing around again. "Well fear not! I believe I have a solution!" Luigi quickly snapped back. "No! I can't trust you, just leave me alone!" Dimentio chimed, "But what if I told you I can get me and Mr. L out of your head?" Luigi's expression softened as he turned to face Dimentio. "Y-You can do that? Why?" Dimentio winked and said, "Well, I just feel awful, seeing you get left behind, and I don't have anything better to do. There is nothing for me to gain here, I just want to help out someone I've wronged in the past. You can help me redeem myself!" 

Luigi was still unsure. "Listen, if you're fine with Mr. L staying in you head for ever while your own brother lives in fear of you, be my guest, but if you want to take my help, then just hear me out." Dimentio loved how suggestable Luigi was. It didn't take much to make him do what you wanted. Luigi looked up and said, "Fine, I'll hear what you have to say, but I make no promises." 

Dimentio giggled, "Okay, I'll guide you through it. This may be a little confusing, but we're going to have to meet one of my friends in order to get me and Mr. L out of your head. He's a little hard to reach, but I've got a plan!"
