Professor E. Gadd's Research Journal is a series of logs and notes written by Professor E. Gadd in the format of a journal, narrated from his perspective, with all the information and events that occurred during his research with a new element discovered called Goo and even the creation of Gooigi. This journal can be found on the official Nintendo website for Luigi's Mansion 3 (here).
The events narrated here occur just after Luigi's Mansion: Dark Moon and before Luigi's Mansion 3. It also explains how E. Gadd manages to contact his past self and Luigi during the events of Luigi's Mansion (3DS) and the reasons for him to do this.
This journal not only shows insight into E. Gadd's process and methods in research, but also reveal various facts about the Goo, Gooigi, other inventions of the professor, and even the reason why E. Gadd even went to The Last Resort in the first place, which lead once again to the escape of King Boo in Luigi's Mansion 3.

Ghosts: spirits that dwell in the darkness and take great joy in scaring humans. Some of these ghosts have grown attached to me, and I've noticed (and collected!) a strange liquid energy from them. I'm certain this liquid is the key to many, many new inventions!
My many experiments failed to reveal anything about this peculiar ghost energy! It didn't react to cold or heat; I tried poking it with iron, pouring it on rubber... I may have even dipped my morning donut in it... All to no effect!
But then, a breakthrought! I was restoring my scientific gusto with an exquisite cup of coffee—a Lunoman Greenie blend from Evershade Valley—when a stealthy ghost snuck up behind me. In my shock, I spilled the entire cup of joe into a vial of the ghost energy and... it reacted instantly!
The ghost energy quickly began changing color, adopting the same green as my finely brewed beverage! After a bit it also gained viscosity, and now it appears to have stabilized into an entirely new element!
I have decided to name this element "Goo." I must return to my research on Goo POSTHASTE!
Goo: The revolutionary discovery that resulted from my entirely scientific tests of the interaction between ghost energy and Lunoman Greenie coffee blend. In order to determine the real-world applications of Goo, I've executed exhaustive research on its characteristics.
My first test exposed Goo to an open flame. I expected no result since ghost energy has never responded to fire, but I was mistaken! Not only did Goo react, it melted away entirely—clearly it possesses a vulnerability to heat.
Logically, I followed my fire test with a water test. I expected a new reaction...but to my surprise, exposure to water caused Goo to melt away as before-suggesting a watery weakness. However! I did notice something different this time...
To my shock, the part of the Goo that had not touched the water—and thus did not dissolve—immediately moved away from the water hazard!
Goo has displayed many other unusual characteristics, as well. When poked or prodded, Goo will actually push back! It also moves toward nearby sounds, displaying some kind of hearing ability. As best I can tell, Goo is intelligently reacting to outside stimuli! I've never seen anything like this before!
There MUST be some greater purpose that Goo can be used for. Once I get another cup of my delicious Lunoman Greenie coffee blend, I'll dedicate all my efforts to figuring that out!
This mysterious element I've come to call Goo has proven unlike any other element I know of. I'm confident that I can make great strides in my research if I can teach Goo to collect ghost for me! My greatest invention, the Poltergust, is undeniably the best way to capture ghosts. I realized that Goo could learn to master the Poltergust if only I could cause it to adopt a humanoid form. The experiments began at once!
First, I created a mold that I could pour Goo into. This went smoothly, and when I removed the mold, Goo was in fact in a human shape! But only a few short moment later, Goo returned to its original form. It seemed Goo was not able to easily hold a shape without help...
It seemed I was at a dead end, until I remembered the biological data that the Pixelator captured when Luigi used it! Taking that data and converting it into an electrical signal, I was able to then input it into Goo. The result was...Exactly as predicted! Goo shapeshifted into an exceedingly green copy of Luigi right before my eyes! I never doubted my genius!
In order to teach Goo, now in the form of Luigi, how to collect ghosts for me, I showed him the vast amount of footage I had of Luigi doing exactly that! Just as I expected, Goo began to mimic Luigi's movements—he even transformed a part of his body into a perfect replication of the Poltergust! This progress has exceeded even my most ambitious expectations! I'm so good I even scare myself!
However, I must keep reminding myself that all great discoveries require a disciplined approach! Progress in the lab is wonderful, but soon the practical test of ghost collecting begins! There's only one more thing to do: name Goo, who now holds the shape of Luigi. Easy! He looks like Luigi, so I shall call him...Gooigi! With Lunoman Greenie coffee blend in hand, I must now determine the perfect place for Gooigi to test his abilities...
Now that I have successfully caused Gooigi to assume Luigi's shape and have taught him to wield the Poltergust, I've decided some practical experience catching ghosts is in order! But where to do that...
I mustn't forget that, if I hope to make use of Gooigi's Goo-based properties to give him capabilities beyond those of a normal person, I'll need ghost energy from beyond Evershade Valley. Thus, sending Gooigi elsewhere could solve both my problems! He would learn more from fighting ghosts, and he could collect ghosts for me at the same time! Heh heh heh!
But where could he accomplish both of these objectives at once? As always, a deep gulp from my Lunoman Greenie coffee blend was just what I needed to think of the answer: the mansion where I first met Luigi! That mansion had been crawling with all kinds of interesting ghosts, so clearly there was no place better suited to this task!
The mansion vanished some time ago, so it would be impossible for Gooigi to just walk there... But this is a problem easily solved! All I had to do was modify the Pixelator to enable it to connect to the past! Simple! With that done, it was just a matter of contacting my past self and Luigi, asking them to help out, and sending Gooigi to them!
After some time, I recalled Gooigi from his adventures to check up on him and... Jackpot! Not only had he succeeded wonderfully at every test and challenge he'd faced, but he'd collected So.Many.Ghosts!
With all of these ghosts in my collection—and a fresh pour of my Lunoman Greenie coffee blend—my mind ran wild with the possible interactions between ghost energies and Goo.
Thanks to Gooigi's adventures in the mansion in the past, I found myself with an ample supply of ghosts from that place! So equipped, I began researching ways to enhance Gooigi's abilities beyond that of any normal person.
The first step was to analyze the energy extracted from the ghosts. Just as I expected, their energy was structurally different from the ghosts of Evershade Valley. Thus, I concluded that there are many types of ghost energy. Some appear to be large molecules tightly bound together. Others are smaller molecules, but no less tightly bound. Still others have only loose connections to one another!
Even with this discovery, I still had to consider what kind of special improvements I could give Gooigi... After all, although Goo is made from the energy of ghosts in Evershade Valley, its properties differ greatly from the ghosts themselves. Unfortunately, this makes it impossible to give Gooigi the same abilities as ghosts, like being able to vanish at will or pass through solid walls.
But perhaps there was something to the viscosity of the Goo itself... Of course! Gooigi's basic makeup could allow him to slip into or through tight spaces, such as grates or fences, while still retaining his human shape! This...this could be the perfect enhancement to his abilities! I daresay it could be one of my greatest inventions to date!
Suitably motivated, I began testing various mixtures of ghost energy and Goo, seeking the perfect combination to alter the Goo's viscous properties. Unfortunately, things did not go as planned. In my initial testing, I found that combining Goo with the loosely bound molecules resulted in it being entirely unable to hold any sort of form. And yet combining Goo with the tightly bound molecules resulted in a rigid substance that couldn't move at all!
Like all successful, accomplished, and brilliant scientist, I continued to experiment! After more tests than I can count, all fruitless, I suddenly had a breakthrough! The final formula seemed to let Gooigi retain his form while giving him a fluid quality when needed. A perfect balance!
I did not hesitate for a moment before applying this new composition to Gooigi. Just as I hoped, Gooigi was able to easily slip between bars or pass through narrow pipes! Heh Heh heh! With my diligent application of science, I was able to create a new, special power unique to Gooigi!
I pictured a gallant Gooigi, master of this newly imbued ability, and I exhaled with satisfaction (and a bit of fatigue). Having pulled off yet another successful experiment, I decided it was time for a break with a fresh cup of Lunoman Greenie coffee blend.
Having succeeded in imbuing Gooigi with his new, malleable ability, I began research into addressing his greatest weaknesses. With his vulnerability to fire or water, Gooigi was not yet perfect...
First, I tried reducing the molecular bonds in Goo, resulting in a mostly liquid version. My theory was that liquid Goo could extinguish the fire, but alas, things did not work out. Although Goo did retain most of its properties while also being that much closer to a liquid, it still melted the moment it contacted the flames.
Next, I decided to try increasing the bonds of Goo's molecules. I'd hardly started my experiment, however, when something unexpected happened! Just as I began to decant the more rigid Goo, that darned Polterpup jumped up on me in excitement, bumping the compound in my hand and sending it flying onto my head! Before I could act, the newly mixed Goo began to run down my body, hardening as it went! This simply wouldn't do! The Goo was already much too rigid for me to peel it off, and as it hardened further over my eyes, nose, and mouth, I found it more and more difficult to breathe!
Realizing the peril of my situation, I rushed from the room! As I gasped for breath, the world around me grew dim...
Some time later, I awoke on the floor of the shower. I still don't remember exactly what happened, but I must have made it to the shower and turned on the water to wash the Goo away. If it hadn't been for its weakness to water, Goo may have been the last thing I ever made!
Not even a near-death experience could stop my inventive spirit, though! I performed hundreds of tests (carefully), but I could not find any way to eliminate Goo's weaknesses... I now believe that there must be something in the process of transforming ghost energy into Goo that generates these flaws. With a heavy heart, I accepted that eliminating these weaknesses was a task beyond even my own genius. Regrettable, but such things happen!
Fortunately, I am gifted at finding the bright side to a poor situation! In the experiments where I varied the stiffness of Goo, I succeeded at improving Gooigi's viscosity! His ability to slip through tight spaces is certainly a selling point, but if he simply fell through every grate he came across whether he wanted to or not... Well, that wouldn't do at all! Thanks to my rigorous testing, however, Gooigi gained the ability to use his own strength to slip through cracks at will!
Additionally, with his new level of viscosity, Gooigi should be able to handle tasks that don't require too much effort, like opening the drawers of a dresser. However, the effort to do things like turning doorknobs and opening doors is too much! Such things are still beyond his grasp. Heh heh heh!
Now then, I should document Gooigi's weaknesses.
Weakness #1: Dissolves upon contact with water or fire. Note that direct contact with liquid H2O will cause this reaction, but rooms containing water vapor or steam do not.
Weakness #2: Loses consistency when struck by powerful attacks. While Gooigi is somewhat resistant to physical blows, he can not hold up to repeated or powerful attacks.
Weakness #3: Can't turn doorknobs. Things that can be opened with the minimum amount of force are fine, such as drawers or treasure chests, however.
I find myself exhausted after my brush with a Goo-y death. I think I'll let the soothing aroma of a cup of Lunoman Greenie coffee blend wash over me as I ponder my next experiment.
After putting my life in danger and ultimately failing to eliminate Gooigi's weaknesses, I nevertheless picked myself up and immediately threw myself into a new experiment.
My new goal? Bending Gooigi's actions to my will!
While Gooigi is capable of independent action, I have noticed on occasion that he can be...unpredictable. Perhaps it is just in his nature as a nonhuman entity, but he does not always act in a sensible manner. For example, no matter how badly I wanted him to sneak up on ghosts, he always ended up brazenly charging forward, scaring them off! If I was only able to control him more precisely, I'm positive I could collect ghosts even more efficiently than before.
With this goal in mind, I embedded a special chip into Gooigi. This chip was designed to let me dictate Gooigi's actions with a controller, and it worked! Gooigi would walk in the direction I indicated as soon as I used the controller. A perfect success! Or so I thought; walking was one thing, but I ran into issues when using the Poltergust.
I pressed the button to signal Gooigi to use the Poltergust's vacuum function, but instead he triggered the Strobulb! After some troubleshooting, I finally got him to use the vacuum, but then he wouldn't stop! He just stood there, sucking up nothing in particular.
I analyzed the controller's algorithm and made change after change to its systems, but nothing seemed to work. Frustrating! However, in my annoyance, I accidentally brushed the controller... Suddenly Gooigi, who was still using the vacuum feature on the bare wall, turned in my direction. Before I knew what was happening, the suction power of the Poltergust had me by the hair, drawing me in!
It was only a matter of seconds before my hair and head were in the nozzle, and I could feel myself being pulled steadily inward! At this rate, I would be undone by my own invention! I struggled and fought in an effort to free myself, but to no avail; the power of the Poltergust is, as it turns out, greater than its creator!
With more than half my head pulled inside, I made my peace and prepared for the end. Just as I did so, however, my foot caught on something on the floor. Before I knew what was happening, I was sprawled out on the ground, free from my high-suction fate!
It turned out that, in my final moments, I had inadvertently kicked a bucked and mop over. The water within the bucket spilled out and melted Gooigi the moment it touched him, setting me free. I cannot express how pleased I am now about my failure to fix Gooigi's weakness to water. Heh heh heh!
Of course, having narrowly escaped death, I took that as a sign to stop what I was doing... Just kidding! I carried on without fear! I did have a new idea to try out, though: what if I abandoned the controller idea and instead worked on developing a way to transfer my consciousness into Gooigi. In essence, I would become Gooigi!
In truth, this idea was related to another objective I was exploring. I'd been thinking about how convenient it would be if Gooigi was stored in the Poltergust when he wasn't in use, and the task of developing a new Poltergust for such a purpose was going well.
Thanks to this new Poltergust, Gooigi could be deployed or recalled at will. With this connection, I pondered whether I could also use the same system to transfer the conscious mind of whoever was wearing the Poltergust directly over to Gooigi!
With the idea burning in my brain, I got to work adding yet one more improvement to this new Poltergust. I attached a sensor to the part of the Poltergust that would touch the user's back, and then tested the system on the only available subject: myself. And everything went as planned! Heh heh heh! By basically becoming Gooigi, I was now able to control his body as if it were my very own!
However, since I had completely transferred my consciousness from my own body to Gooigi's, my body appeared to enter a sleep-like state so long as I was operating Gooigi. Oh well! It is a minor hinderance at best, and well worth this new ability, especially since this system allows me to quickly transfer my consciousness between myself and Gooigi. If either body is in danger, I can quickly switch between them to deal with any issues.
And thus the new-and-improved Poltergust was complete! Storing Gooigi, transferring consciousness... There was much to celebrate! And as always, I did so with a wonderful cup of my Lunoman Greenie coffe blend. At the same time, a letter arrived for me...
It was an invitation sent by the owner of a luxurious hotel in a region long thought to be home to extremely rare ghosts. And the owner was inviting me to stay there, free of charge!
It seemed the owner had a keen interest in seeing King Boo, who Luigi captured for me during the crisis in Evershade Valley. He'd been a part of my collection ever since, and the owner of the hotel said she would happily compensate me if she could see him face-to-face! In fact, she wrote that, if I were to bring King Boo along with me on my hotel stay, she'd give me her priceless ghost collection...free of charge! What an amazing opportunity! Such a simple request to expand my collection? How could I say no?!
With a spring in my step and my head filled with dreams of adding even more new ghosts to my collection, I packed up the new Poltergust and Gooigi, along with a Boo Canister containing King Boo, loaded the lot into my car, and set out for the hotel...
Trivia[]
- The journal reveals that during this research, E. Gadd almost died two times. The first one caused by Polterpup and the second one by Gooigi, both of them by accident.
- It is unknown what or who really turned on the shower that saved E. Gadd's life in the first incident.
- The power of the copy of Gooigi's Poltergust 5000 is so strong that it's even capable of sucking up humans, not only ghosts.
- Ironically, E. Gadd's failure to eliminate Gooigi's weaknesses to water is what saved his life the second time.
- E. Gadd still has several pieces of footage of the adventures of Luigi during Luigi's Mansion: Dark Moon.
- During the process of documenting Gooigi's weaknesses, E. Gadd almost shows no empathy towards Gooigi, as seen in the polaroids.
- E. Gadd mentions that he embedded a special chip into Gooigi. The exact location of this chip is unknown, as it's not seen in-game either.
- One of the pictures used in the website is titled "Guigi.png", misspelling Gooigi's name.
- Another doodle of Gooigi is named "Luigi-notes.png" instead, probably mistaking one character with the other.
