"What troubles you my dear" Luigi overhears E. Gadd talking to Daisy.

"It's nothing professor" she sounded worried.

"It's didn't sound like nothing, something is troubling you, what is it"

"It's just Luigi I'm just worried about him"

"You don't need to worry about him, he's a super Mario brother after, if he can defeat bowser he defeat king boo too, but I have a feeling it's not Luigi you're worried about...is it?"

"No"

"Then what's wrong?"

"There's something I haven't been entirely true to Luigi"

"What is it, you can't tell him, I don't want him to find out, if he knew, he wouldn't handle it"

"Trust in me my dear. Nothing comes out of this lab, just between you and me"

"Ok, the thing is....my pregnant"

"What?" Luigi was shocked, Daisy was pregnant, "he didn't know how to handle it"

"Oh this is amazing" E. Gadd says.

"Yeah but-I wanted to tell him but I don't think he's going be ready, and I'm worried he's gonna leave me"

"No, Luigi is better then that"

"You have to promise me you won't tell Luigi, not until this is over"

"Don't worry my dead I promise I won't say a thing, but you will have to tell him sooner or later"

"I doubt he would understand"

Luigi suddenly realized it, what she meant in the bedroom, sissy's worries has him feeling guilty, of course he would understand but he's afraid that his own child wouldn't like him.

So he pretends like he didn't heard, and came right in.

"Luigi?" Daisy looked shocked when she saw a concerned look on his face.

"Professor! I've got your case!"

"Welcome back, you two!"

Luigi handed E. Gadd his briefcase, "Hehehe! This! This is what i wanted! The time has come to use these in battle! I'm too old to be out catching ghosts by myself. Rather than give up on my ghostly pursuits. I thought l'd create helpers to take my place"

"Helpers? What kind of helpers?" Luigi asked.

E. Gadd opened his case and took out one compartments. One was filled with green goo.

"Uh, what is that?" Luigi asked.

"The latest invention from the brilliant mind of Professor E. Gadd! I give you... Gooigi The development process was a real challenge, to say the least. Fortunately, I had a little help from... someone to test the prototype!"

"How's it going to work?"

"E. Gadd: Now, now. Take it easy. Here. I'm going to attach this to the Poltergusts. Turn around for me"
He turned around and E. Gadd inserted the compartments.

"Ok! It's all set up! Let's practice a bit, follow me outside"

They followed him outside. A cage was above him, but what he didn't know was E. Gadd pressed the button and down the cage went. The two of them were shocked.

"Professor?!" Daisy shouts.

"Hey!" Luigi says.

E. Gadd gave Luigi a thumbs up.

"Hehehe! I've caught in my trap"

"Yeah I can see that" Luigi shouted.

"Oh, don't worry! I'm just kidding! But I am going to need you to stay locked up"

"What? Why?!" Luigi groans.

"Because I want you to use Gooigi to try to escape from your cell!"

"But how do we... you know....how am I supposed to do that" Luigi cried.

"To release Gooigi you have to press the buttons on the side of the tank.

"Like this?" Luigi pressed on his button and released Gooigi, Luigi let out a yell. He fell limp but he still were standing up.

"ah! What is that?"

"Ta-da! Behold! This is your very own personal assistant, Gooigi!"

"Ok but what does it do"

"He can slip through tight spaces, like grates or vents. Her body is incredibly soft and malleable. It's really quite amazing!"

Daisy was looking back at him. It looked like he was sleeping.

"How does Gooigi move" Luigi asked.

"can Luigi still hear us?" Daisy asked.

"Don't worry, Luigi can still hear us. For Gooigi to move, you have to control it with your mind" When E. Gadd said that, Gooigi started to move. He slipped through the bars.

"Whoa!"

"There you go, Luigi! He moves in basically the same ways everybody does, so controlling him shouldn't take much getting used to. Oh, and that reminds me! Pressing the button again makes him go back into the compartment. Remember that!"

Gooigi started moving toward the lever, but when he got there, he melted. Once he has melted, Luigi bolted his eyes up and looked around.

"Oops, looks like Gooigi are not exactly waterproof, so keep them away from water"

"You're telling me, Got it!"

Luigi pressed your button again and out came Gooigi running towards the lever and walked around the water. There he pulled the lever and out came Luigi.

Luigi walked out of the cell. And pressed the button again on the side of the tank.

"All right! We're done with your training, at least for now. Let's go bad to the lab"

"Come on polterpup" Luigi whistles for him.
