"Alright, I'll check out your brain right now.", you said, "I'm sure there will be a lot to see in there."
"Go ahead. You'll be blown away by the sight..", Luxray said playfully.
From the second floor of Luxray's 'head chamber', the brain is huger than you imagine, possibly able to accommodate a large Pokemon gym you visited a few months ago. The second floor also gave you a good view of the two windows (Luxray's Eyes) you saw earlier. The Luxray now seem to be traveling in a beautiful meadow within the forest. You momentarily paused to see the beautiful flowers and trees before continuing your way toward the brain. Arriving at the front of it, you see no apparent placed from where you can enter.
"Uh-mm...Luxray, how exactly can I enter your brain to control you since I see no entrance around here?", you asked.
"You can enter it by using the countless folds outside my brain, any of them would do the trick.", replied Luxray.
"Thanks for telling me.", you said as you approach a large fold near you. You entered the crevice and make your way literally toward the center of Luxray's brain. The brain walls sort of squish you tightly, but it allows just enough room for you to move sideways. After traveling for what you think is 5 minutes, you arrived at a small room somewhere in the brain. You take your time to look at your new surrounding. The floor of the room is kinda squishy and has a lot of small crevices from the fact that the chamber is in the brain. The room is lit by the same kind of light bulb-like fixtures you saw throughout Luxray's body, powered by the Pokemon's internal electricity. Near the center of the room, there seems to be a circular dome of a darker shade of pink. You went over to take a closer look at it. From the size of the dome, you believe that it probably can only allow for one person to stand on and use. Before you can open your mouth to ask the Luxray, the Pokemon's voice reached you head, sounding loud from the fact that you are at the "center" of Luxray.
"I sensed that you have arrived at the 'command center' in my brain.", the Luxray said, "And you were asking about how you can control for some time, right? Well step onto the 'control dome' and I'll tell you more."
You made your way toward the dome you saw previously and you making your way to the top. The flesh and the slime has made it a bit difficult for you to ascend the dome. Once you reaced the top, you find that there is a small depression that you can get into. You move yourself toward that place. Almost immediately, several strands of 'brain muscle' materialize from the wall of the brain chamber. The cord-like strands are about 1ft in diameter and covered with red veins. The next thing you saw is the strands are latching unto your hands and legs, completely surrounding them as if you are wearing gloves and socks. Strangely enough, the "gloves" and "socks" gradually change their shapes into Luxray's paws and hindlegs, complete with black and blue fur. Despite the addition of the strands, you discover that you can still freely move around on the dome. Then, the Luxray begin to speak again.
"Okay, it looks like you're ready.", said the Luxray telepathically, "Don't worry about those things that i've attached to you. They are for sensing your movement to control me. Both the dome and those muscle strands are part of the control mechanism within me. All you have to do now is to get down on all four and you're good to go.
You did as Luxray instructed, falling down on your legs and arms, making it look that you're crawling. Immediately, the chamber around you suddenly brighten up and you saw a wide (180o) view of Luxray's vision, showing the field you saw previously; you assumed that the images are transmitted from the 'head chamber' outside and merged to form this "IMAX screen". But you can also feel and hear the winds around you as if you're actually a Luxray.
"Let me explain a little about how to control me. To move me around, you just have to move your arms and legs in the desired direction; all my movements at this point will be exactly what you are doing right now.", you hear the Luxray said, "Basically, you're now temporarily me. But for your and my safety, you can only control my movement and you have to remain in this field; currently, you cannot use any of my powers and abilities. We'll get to that when you familiarize yourself with me over the long term."
Despite being unable to use any of Luxray's ability, you are already excited about controlling the Pokemon. After a few tries, you learned to walk and run on four legs. The experience is awesome. It gives you a sense of being "wild". You run around the fields for an hour, chasing some Bug Pokemons and randomly sprinting about. Eventually you got exhausted and tired. you tell Luxray that you want to rest. Almost immediately, the Pokemon re-assumed control of his body.
"You are kinda good at running and sprinting; you probably even be an excellent Pokemon if you ever were one.", the Luxray said, "There are many other parts in my brain that contains a lot of things you would like or do you wish to explore other parts of my body."
