Looking the Luxray's wide-open mouth, you still ponder about whether to enter. You have just met this Pokemon for a little more than half an hour ago and you are still unclear with the situation surrounding you. But you realized that the Luxray has a point: you are now small and vulnerable, and the fact is you'll make a good prey among the many wild Pokemons in this forest.
After thinking about all the other possible options, many of which are unrealistic in your opinion, you decided to take your chance with the Luxray. Together, you both with find time to figure out the why you were shrunk?
"Here I go.", you said.
"Enter...and enjoy..human.", the Luxray said enigmatically.
Slowly, you walked toward the Luxray's mouth and onto the pink tongue before you. It is soft, slimy, and cover with drools. You feel yourself slightly trembling because you have never literally 'enter the belly of a beast' before. You eventually come to the gullet. You looked down and saw a dark fleshy cave that extends deep down into the Pokemon. Normally, this passage is reserved for food and other unsuspecting preys to meet a gruesome end in the stomach . But today, it will become the entrance to your new, organic "home" in Luxray.
You gathered your courage and started to walk down the slippery floor of the gullet. Before going deeper, you turned your head back to the entrance. From this vantage point, Luxray's fangs and teeth framed the forest outside, making you wonder whether this is the last sight that preys would see before they die.
Realizing that you are fully in his mouth, the Luxray slowly closed its gaping jaw, engulfing you in near darkness. You continue to descend down esophagus, feeling the walls around you pulsating to the sound of gentle heartbeats. From your perspective, the "passage way" is about 15 feet wide and 7 feet tall. As a way of mitigating your uncertainty, you imagine that you are just traveling in one of the countless dark tunnels that you encountered on your journey to be a Pokemon Master.
You traveled downward for another 5 minutes before you finally reached the stomach. The end of the esophagus is so slippery that you lost your balance and slide right down into the stomach, falling onto spongy floors and some liquids. Besides that, there is nothing else. No acids, no undigested stuffs, spotless.
"Hi, trainer, are you finding my stomach rather comfortable? Again, I will not digest you in there. Feel free to explore around and if you got questions, feel free to ask me.", said the Luxray.
"Wait a minute, didn't you just said that you are already full? Then why is your stomach completely empty?", you asked.
The Luxray gave you a little laugh..:"Ha ha....I was just using a figure of speech you humans would understand. As a Luxray, my primary source of food is sunlight and electricity. That leaves my 'extra' organs like my stomach capable of other uses, like allowing a human to live in me."
"That explains a lot.", you said.
You take a closer look at Luxray's stomach. It's the size is about a large bedroom. You decided to lie down for a short rest on the soft floor. Then, something strange caught your attention.....There are three holes in Luxray's stomach. Seeing this, you inquire the Pokemon.
"I forgot to tell you something", said Luxray, "There are three areas you can go in my body: A Personal Stomach, My "Center", and some parts of my bowels and reproductive organ. In short, here are some basic info:
--Personal Stomach: Your private living quarter.
--My "Center": An 'observation deck' for a Pokemon experience. Experience Luxray first hand.
--The third part is self-explanatory
"Are you going to rest for while or do you want to know me a little better?", asked Luxray affectionately.
